I know I can get things done, no matter the challenge. But how do I do it effectively? That question has been on my mind for a while now. It's no longer about proving my capability to accomplish something, what's been driving me lately is a more subtle (and deeper) unease: the desire to do better! Capability Isn't the Hurdle If you work in tech, you've probably gone through the phase of learning new tools, frameworks, languages, and methodologies. In the beginning, the challenge is always about making it work. But after some time, something shifts. Execution stops being the obstacle, and a new question pops up: "Okay, I can do it. But is it actually good?" The Unease That Propels This kind of restlessness signals maturation. It's when you stop measuring your work solely by the number of co…  ( 4 min )

Remote team collaboration is no longer just a trend. It’s how modern teams get things done. But working from different locations can bring its own set of challenges, especially when communication, engagement, and accountability start to slip. What is Remote Collaboration? Remote collaboration is the process of working together toward shared goals while being physically apart. It relies on digital tools, such as video conferencing, shared documents, messaging apps, and virtual polling, to facilitate effective communication and keep projects on track.

When I started building web apps with PHP and Laravel, my main goal was simple: make it work. 🧠 What is Clean Architecture? The core business logic is independent of frameworks and tools. Your app becomes easier to test, maintain, and evolve. You can plug and replace things (like Laravel, databases, external APIs) without touching your core logic. 🧱 The Layers and The Golden Rule Domain Layer: Entities, business rules. The heart of your application. Application Layer: Use cases that orchestrate the domain objects. Infrastructure Layer: Frameworks (Laravel), databases (MySQL), APIs, queues, etc. Interface/Presentation Layer: Controllers, CLI Commands, anything that presents data to the user. The most important rule is The Dependency Rule: source code dependencies can only point inwards. T…  ( 5 min )

Hi, I'm Dhamith, a software engineer with over 2.5 years of experience. But back when I was an undergraduate, I faced the same challenge many students face today, finding an internship. These days, it's tough. There's lots of competition, few responses, and endless applications. That's exactly why I'm sharing my story. I didn't land my internship through a job portal or by sending out resumes. It came from something completely different. Here's how it happened. In the beginning, I built a few hobby projects just for fun. Simple things I was curious about or wanted to try. I didn't expect much from them, but I shared them anyway on social media. At first, I posted my work everywhere Twitter, Facebook, and LinkedIn. But after a while, I started noticing something, LinkedIn was where my work…  ( 5 min )

While working with Git branches like develop and main, it's common to frequently merge changes. But did you know that doing so with regular merges can break a linear commit history? Here's what I learned today 👇 If you keep merging from develop to main using regular git merge, Git will create merge commits, leading to a non-linear (branched) commit history. This can make git log harder to read, especially in large projects. To ensure a clean, straight commit history on main, use one of these strategies: Rebase Before Merge git checkout develop git rebase main # Replay develop commits on top of main git checkout main git merge --ff-only develop # Fast-forward only ✅ This avoids merge commits and keeps the history linear. Use Squash Merging (Optional) If you want to combine all develop changes into a single commit before merging: git checkout main git merge --squash develop git commit 🎯 Useful for condensing work into one clean commit. Use Fast-Forward Merges Only Prevent accidental merge commits: git merge --ff-only develop 🔁 Repeat this pattern consistently to keep main clean and linear — great for production branches and readable history.

This is a submission for the World's Largest Hackathon Writing Challenge: Building with Bolt. I graduated from university last year with a Philosophy degree — but for me, philosophy isn't just a qualification written on paper. It’s how I try to live, think, and grow. So, I thought: What if people could interact with a philosopher by simply speaking to one — just like we imagine having a chat with Socrates? That’s what led me to create Ask a Philosopher — an AI Voice Agent that listens, thinks, and speaks back. It was built using the following stack: 🎨 Frontend: HTML + JavaScript + WebAudio API + Text-to-Speech 🧠 Backend: Flask, hosted on AWS EC2 🔌 External APIs: AssemblyAI for Speech-to-Text + Gemini API for philosophical responses 🚀 Deployment: Single EC2 instance with Nginx as a reve…  ( 5 min )

Account abstraction has been a hot topic in Ethereum development for years, and ERC-4337 finally brought it to life. USDC or USDT because you lacked just a bit of ETH for gas fees, you're not alone — and ERC-4337 is part of the solution. If I got a cent every time I asked a friend for ETH just to send a stablecoin, I’d probably have ten dollars by now. Let’s say you’re holding only USDT in your wallet. You want to send it to a friend. But wait, you need ETH for gas. Suddenly, you’re scrambling to: Bridge or buy ETH Beg friends for a top-up Or worse, use a centralized exchange,cmon😖 This UX is not friendly, especially for everyday users or newcomers.

Introduction Launching a successful token presale is not just about having a great product or tokenomics—it’s also about building momentum, trust, and community engagement. One of the most effective ways to achieve this is by leveraging a revenue sharing model as part of your presale marketing strategy. This approach incentivizes community members, influencers, and promoters to actively participate in and promote your presale, creating a win-win scenario for all parties involved. A revenue sharing model in the context of a token presale is a system where a portion of the funds raised (or tokens sold) is distributed as rewards to promoters or referrers who help bring in new investors. This model transforms your community into an active marketing force, aligning their interests with the su…  ( 6 min )

There's been a flood of demos lately showing off how MCP servers can write WhatsApp messages or book plane tickets. Most of that feels like novelty, not utility.

Who Built It? How Proof of Attribution Gives Credit Where It’s Due In traditional software development or AI research, it’s easy to overlook one crucial question: Who actually built this?

Content might be pulled from the web, cleaned, annotated, and prepped by unseen hands. Yet, when the product goes live a chatbot, a new algorithm, a predictive tool credit is often centralized. The work of contributors gets buried under logos and branding.

Have you ever wished that you could learn a new language just by browsing the web? Well I know I have. About a year ago I decided that I wanted to learn Russian. Learning a new language is a slow process, so being able to spend time constantly working towards this goal is critical. However once the novelty of embarking on a new hobby wore off I found it harder and harder to engage and enjoy what I was reading, children stories just aren't that entertaining. This lead to me thinking, I wish I could engage with Russian the same way I do English every day.

Originally published here: Due to a lack of tutorials about setting up ESLint with Vite and React, especially including React Hooks and React Refresh, I've written this guide to help developers looking for such resources. Let's get started! This tutorial assumes you are using Vite 7, but the instructions should be applicable to other versions as well. In case you aren't very familiar with ESLint, Vite, or React Refresh, here is a bit of info about each.

Wave provides a feature called inline assembly, and today we’re going to use it to directly call the BIOS. The int 0x10 interrupt is one of the most basic video output functions in real mode. By putting 0x0E into the AH register and the character you want to output into the AL register, then calling int 0x10, the BIOS will display the character on the screen. Using this method, we’ll print "Hi!", then perform a line break with CR (0x0D) and LF (0x0A), and finally print "OK". Currently, the Wave compiler can only be built on Linux, and by default it only generates executable binaries. It does not directly create a .img disk image like a bootloader would. However, when Wave compiles, it generates a /target folder that contains both an LLVM IR file (.ll) and a Linux binary. Since we want to c…  ( 5 min )

🧭 Day 2: Kicking off Auth Service – Exploring Keycloak vs. Duende IdentityServer In our journey to build a robust, secure, and scalable e-commerce platform (SmartKart 🛒) using .NET Core and Microservices, we are now diving into the Authentication and Authorization layer. Why Start With AuthService? 🔍 What is Keycloak (in simple words)? Keycloak is an open-source identity and access management tool. Think of it as a central place where: Users register and log in 🔑 Roles and permissions are managed 🛡️ Tokens (JWT) are issued for secure API access 🧾 And the best part? It already has all the features built-in — you don’t have to code login pages, password management, token handling, etc., yourself! ✅ Why We Chose Keycloak Over Other Options ASP.NET Identity + JWT (custom) Duende IdentityServer (formerly IdentityServer4) Keycloak Here's why I picked Keycloak: ✔️ 1. Fully Open Source ✔️ 2. Feature-Rich, Out of the Box ✔️ 3. Centralized User Management Add/edit users Assign roles Configure clients/apps ✔️ 4. Standards-Based Protocols ✔️ 5. Easy to Integrate with .NET Core JWT Bearer Authentication OpenID Connect client libraries ✔️ 6. Scalable & Cloud-Friendly 📌 Summary Comparison Table : Feature Keycloak ✅ Duende IdentityServer ❌ Open Source (free to use) ✔️ Yes ❌ No (requires paid license) Admin UI for users/roles ✔️ Built-in ❌ Needs custom development Login/Register/Forgot UI ✔️ Provided ❌ Build yourself Protocol Support (OAuth2/OIDC) ✔️ Yes ✔️ Yes Easy .NET Core Integration ✔️ Yes (via JWT/OIDC) ✔️ Native Multi-tenant support ✔️ Realms ❌ Manual effort  ( 3 min )

Background I am a developer. I love coding. But lately I started to be interested in this so called "Vibe coding". You know, on LinkedIn I see people claiming that they can do a complete application in hours, put them to market and don't need to hire developers. Now that I did some some experiments doing "vibe coding" I noticed that yes, it helps a lot, it makes some things faster, you don't have to do a lot of the big stuff, just focus on the solution and in the parts where you really have to think. My first experiment was doing an Android app called "Card Umen". My experience with Kotlin is almost zero (I made something for a hackaton in the past but forgot almost all), so I worked with chatgpt, claude and gemini and yes, they made a bust on productivity but I needed to be there all t…  ( 5 min )

Java Inheritance is a fundamental concept in OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class. In addition, you can add new fields and methods to your current class as well. class ChildClass extends ParentClass { // Additional fields and methods } Code Reusability: The code written in the Superclass is common to all subclasses. Child classes can directly use the parent class code. Method Overriding: Method Overriding is achievable only through Inheritance. It is one of the ways by which Java achieves Run Time Polymorphism.…  ( 4 min )

Blockspace refers to the finite capacity within a blockchain block that is available for storing transactions and other data. See a blockchain like a digital ledger (it's more than this anyway), and each "block" as a page in that ledger. Blockspace is essentially how much "writing room" is available on each page. This space is a critical resource because, Limited Supply: Every blockchain has a maximum block size (measured in bytes or gas units) that dictates how much data can fit into a single block. This limit is set by the protocol to manage network load, prevent spam, and ensure decentralization (as larger blocks are harder for nodes to process and store). High Demand: As blockchain networks gain adoption, there's increasing demand from users and applications to include their transact…  ( 5 min )

This is a submission for the Algolia MCP Server Challenge An AI-powered learning dashboard with a React/Vite frontend and a Flask backend. Users can upload PDFs or submit web links - the backend processes will extract text (using pdfplumber for PDFs and Jina Reader for web links), then enrich with AI-generated summaries and key points via OpenAI. All enriched data and metadata are indexed in the Algolia MCP Server, enabling fast, unified, and semantic search across all resources. The system also securely manages user authentication with AWS, allowing users to search, review, and download their learning materials with ease. Deployed Link: https://study-documents-fe.vercel.app/login *Github Repo: * https://github.com/sakshi30/study_documents_fe https://github.com/sakshi30/study-enhancement-bknd Demo: https://drive.google.com/file/d/1AhO3UQ-9s43K_jO6AXwx7yfeQRU9HRJb/view?usp=sharing Screenshots: I utilized the Algolia MCP Server as the central indexing and retrieval layer for all the learning materials my users upload, including PDFs and web links.

What is it? A data warehouse is a central store used for managing large volumes of historical and current data for an organization. Unlike operational and transactional databases, it is optimized for analysis and business intelligence. This is the core storage component in a data warehouse built upon a data model. Dimensional modelling is the preferred method of coming up with the blueprint/data model for this database because it is both query optimizing and easy to grasp i.e. Fact table for quantitative measurable metrics and dimension tables for descriptive/attribute content adding meaning to fact tables. Star schema: simple and intuitive. It is denormalized, query optimizing, compatible with reporting and BI tools but storage inefficient. Snowflake schema: complex and extends star sc…  ( 5 min )

3480. Maximize Subarrays After Removing One Conflicting Pair Difficulty: Hard Topics: Array, Segment Tree, Enumeration, Prefix Sum, Weekly Contest 440 You are given an integer n which represents an array nums containing the numbers from 1 to n in order. Additionally, you are given a 2D array conflictingPairs, where conflictingPairs[i] = [a, b] indicates that a and b form a conflicting pair. Remove exactly one element from conflictingPairs. Afterward, count the number of non-empty subarrays1 of nums which do not contain both a and b for any remaining conflicting pair [a, b]. Return the maximum number of subarrays possible after removing exactly one conflicting pair.

Disclaimer: AI was used for checking grammar and to improve readability. Content was written by human. Just a quick story that happened yesterday and perhaps a warning to the vibe coders out there. As the title suggests, I too tend to vibe from time to time. When I do, I go all out and allow the agent to commit its changes. I use a git-mcp-server for this (see https://github.com/modelcontextprotocol/servers/tree/main/src/git), which does a great job until I noticed some strange behaviour during a disastrous vibe coding session. After the agent committed everything, there were still some staged files.

A data warehouse is essential for consolidating and transforming data from multiple sources into a single, reliable source for business intelligence, reporting, and analytical insights. It is a subject-oriented (focused on specific business areas like sales, customers, or products), integrated (combines data from multiple sources into a unified view), time-variant (stores historical data), non-volatile (data is usually not deleted from a warehouse) collection of data to support decision-making. Implementing a data warehouse offers many benefits: Replaces manual data gathering, significantly reducing human error, and increasing speed through ETL (Extract, Transform, Load) processes. Becomes the single source of truth for all analysis and reporting, ensuring consistency across the organizati…  ( 11 min )

Have you ever wondered how the code you write transforms into a running program? If so, you’re in the right place. A compiler is a powerful tool that translates human-readable source code into assembly language, a medium-level representation that a computer can process. The compilation process involves several crucial steps, including lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, and code generation. That’s about the flow of phases during compilation. Let’s dive deep into each phase now. Lexical analysis is the phase where the source code is broken down into tokens. Tokens include keywords, identifiers, operators, and delimiters. Each token is saved into a data structure called the Symbol Table. Each entry is stored in the following…  ( 7 min )

(Първо публикувано на 12.01.2017) При днешния алгоритъм е по-интересна имплементацията, отколкото приложението му на ръка. Това е един класически числов алгоритъм за намиране на прости числа в интервал и определено си струва да го добавите към “арсенала” си. 😉 Очевидно е, че брадата прави играта… :) ОПИСАНИЕ: “Решетото на Ератостен” (да, решетоТО, а не просто решето :)) се използва за намирането на прости числа (т.е, числа, които се делят само на 1 и на себе си) в даден интервал. Името идва от думата “решето” — съд с дъно на дупки, през които отстраняваме ненужното (правили сте си спагети, нали?). По същия начин, с този алгоритъм премахваме числата, които не отговарят на условието да са прости и след това филтриране получаваме резултата, който ни интересува. Този алгоритъм е подходящ за …  ( 5 min )

Introducing Today's Project! What is Amazon VPC? How I used Amazon VPC in this project One thing I didn't expect in this project was... This project took me... VPCs are virtual private networks within the AWS cloud that give you private, customizable control over how your cloud resources connect and interact. Without VPCs, all your resources would float in one massive open space online, with no privacy. AWS sets up a default VPC! This is why I could launch some resources like EC2 instances and connect services together from Day 1 of using AWS. If it didn't exist, I would've had to learn how to create a VPC before I can use services that require it. To set up my VPC, I had to define an IPv4 CIDR block, which is a range of IP addresses that my resources use to identify and communicate with…  ( 4 min )

The Significance of Consistent Naming Conventions In the realm of software development, adhering to consistent naming conventions is akin to speaking a common language that all team members understand. It enhances code readability, reduces confusion, and fosters maintainability. Best Practices for Consistent Naming Conventions 1. Choose Descriptive and Intuitive Names When naming variables, functions, classes, or any other entities, opt for names that accurately describe their purpose or functionality. Avoid cryptic abbreviations or overly generic terms. Example: int numApples; // Good int n; // Poorly named 2. Use CamelCase or snake_case Consistency in naming styles is key. Whether you prefer CamelCase (e.g., myVariableName) or snake_case (e.g., my_variable_name), stick to one convention throughout your codebase. 3. Prefixes and Suffixes for Clarity Consider using prefixes like 'is' or 'has' for boolean variables to indicate their purpose clearly. Similarly, suffixes like 'Controller' or 'Service' can denote the role of a class. 4. Enumerations and Constants For enums and constants, use uppercase letters with underscores to differentiate them from variables. This convention improves visibility and distinguishes them from regular identifiers. 5. Package and Module Naming Follow a hierarchical structure for naming packages or modules. Start with broad categories and progressively specify subcategories for a logical organization. 6. Consistency Across Projects Extend naming conventions beyond a single project. Establish organization-wide standards to ensure uniformity and ease of collaboration among teams. Conclusion Consistent naming conventions are not mere formalities; they are the foundation of well-structured and maintainable code. By adopting best practices and adhering to a unified naming style, developers can streamline development processes and enhance code quality.  ( 4 min )

Last Tuesday, I watched a senior developer at my company spend 15 minutes just figuring out where to update a simple task status. Slack for team discussion, Jira for the ticket, Linear for sprint planning, GitHub for code review comments, and Notion for project documentation. By the time he updated everything, he'd completely lost his train of thought on the actual code problem he was solving. Sound familiar? We've created a monster. In our quest to optimize every micro-process, we've built workflows that would make a 1990s enterprise jealous. The average developer now juggles 9-12 different tools daily, and we wonder why that "simple" feature took three weeks instead of one.

As developers, we often joke about “bad posture being part of the job.” Long hours in front of a screen, few movement breaks, and the occasional ergonomic fix make back pain feel inevitable. And when it hits, most of us grab a heat pad and hope for relief. But what if that very habit is silently working against us? Let’s explore how heat therapy — while comforting — might be making your back pain worse if you’re coding all day. We’re built to move, but coding doesn’t require much physical activity. Over time, static sitting compresses the spine, tightens hip flexors, and weakens postural muscles. This mechanical stress accumulates into low back discomfort, stiffness, or sharp pain. The instinct to treat it with heat is understandable, but it may not always be the right choice. Heat increas…  ( 4 min )

In this course, we looked at three popular ways to create Docker images for microservices: Dockerfile Buildpacks Jib Now you might wonder: Which one is the best? there is no one "best" method. Each has its own pros and cons, and your choice depends on your specific needs. ✅ Pros: Gives maximum control and flexibility. You can customize it to fit almost any requirement. ❌ Cons: You need to write and maintain it yourself. You must know best practices for performance and security. Each microservice needs its own Dockerfile. ✅ Pros: Easiest to use — no need to write Dockerfiles. Supports multiple languages (Java, Python, Node.js, etc.). Great for multi-language microservices projects. Offers features like caching, modular builds, and security metadata. ❌ Cons: Slower and uses more memory, especially on local machines. Has some performance issues on macOS. ✅ Pros: Designed specifically for Java projects. Very fast and lightweight — saves memory and disk space. Works smoothly across Windows, macOS, and Linux. ❌ Cons: Only supports Java. Less flexible compared to Dockerfile for complex setups. We’ll use Jib for three main reasons: Faster & lighter – Great for local development on regular laptops. Our microservices are Java-only, so Jib is a perfect fit. Fewer issues on macOS – Buildpacks can be slow or buggy on Macs. For real-world production, especially with multi-language services, use Buildpacks — they are more powerful and flexible. If you're working with Java-only and want a quick, easy setup, Jib is a great choice. If you need full control and have special requirements, use a Dockerfile. 👉 There’s no “bad” option — just choose what fits your project and team best.  ( 6 min )

If you're building a music app with on_audio_query, it’s tempting to call querySongs() everywhere—home screen, playlists, search, etc. But this means repeated storage scans → slower UI, battery drain, and unnecessary complexity. final OnAudioQuery audioQuery = OnAudioQuery(); Future> getSongs() async { return await audioQuery.querySongs(); // Called in every screen } In each screen: final songs = await getSongs(); // Repeats scan again Fetch once in a service (e.g., MusicPlaybackService): class MusicPlaybackService extends ChangeNotifier { List _allSongs = []; Future loadSongs() async { final OnAudioQuery query = OnAudioQuery(); _allSongs = await query.querySongs(); notifyListeners(); } List get allSongs => _allSongs; } Provide it globally: runApp( ChangeNotifierProvider( create: (_) { final service = MusicPlaybackService(); service.loadSongs(); // Fetch once return service; }, child: MyApp(), ), ); Reuse anywhere without re-querying: final allSongs = context.watch().allSongs; Benefits No repeated disk access.

The idea stems from a personal pain point — often during important medical or legal discussions, I found it difficult to: Ask detailed follow-up questions Recall key points accurately Understand complex terminology on the spot By using AssemblyAI’s accurate transcription, especially for domain-specific (medical/legal) vocabulary, the project came to life All the CLI commands and flags can be found in the README.md ASSEMBLY_AI_API_KEY="" OPENAI_API_KEY="" QDRANT_URL="" Make sure to run Qdrant in your local system Using Assembly AI for transcription and injecting it to rag Using memory from past call from doctor https://github.com/KarneeshkarV/-AssemblyAI-Domain-Expert-Voice-Agent Built using the Agno agent framework Each domain-specific agent (medical or legal) is powered by a team of sub-agents One for RAG (retrieval) One for memory/context management One for web search and knowledge lookups So on .... I used OpenAI models in the primary implementation due to cost-effectiveness, though I found Claude models to perform better in tool use during testing Made some audio optimizations to effectively use TTS credits Core transcription powered by AssemblyAI, enabling robust handling of domain-specific vocabulary Future Work I had plans to: Make the entire injecting of data more easier and user Friendly Integrate SIP Sorcery for capturing and analyzing VoIP call streams Add another specialized agent focused on legal document processing However, due to my time constraints — they remain on my Todo list! I am all hears to know how I can improve this project  ( 4 min )

When building backend applications with Express.js, handling errors properly is crucial. It not only helps you debug issues quickly but also ensures a better experience for users when something goes wrong. In this blog, we'll walk through how error handling works in Express, why it matters, and how you can implement it in your own projects. Error handling is the process of catching and responding to errors in your application. These errors could be anything from a missing file, a bad request, a database failure, or even a typo in your code. Instead of letting the app crash or return confusing messages, we use error handlers to catch these issues and return useful responses. Express has a special kind of middleware just for errors. This middleware function must have four arguments: err, req…  ( 5 min )

Most of the stock back-testing tools and libraries I've seen are either too complex for beginners or have a steep learning curve. So I decided to build my own Python library from scratch called stocksimpy which aims to be a light-weight and well-documented alternative to what is out there. One of my primary goals with this series is to learn how Python libraries work, as well as to improve my skills in Pandas and NumPy. And create something that could grow into a real tool for others to use. In the process, I ended up implementing over 10 indicators from scratch. Here’s how I approached, what I learned, and how you can do the same: This is a valid question. I also asked myself this when I reached about 300 lines of code.

Inheritance is a powerful feature in Object-Oriented Programming (OOP) that allows a class to reuse the properties and methods of another class. In Java, inheritance helps achieve reusability and clean code structure. There are five types of inheritance. One child class inherits from one parent class. Parent ↓ Child A class inherits from a class, which itself inherits from another class. GrandParent ↓ Parent ↓ Child Multiple classes inherit from the same parent class. Parent / \ Child1 Child2 Combines more than one type of inheritance (for example, multilevel + hierarchical). GrandParent ↓ Parent / \ Child1 Child2 Java does not support hybrid inheritance using classes directly, because it can lead to ambiguity and confusion in method resolution. A class attempts to inherit from more than one parent class. Parent1 Parent2 \ / Child Java does not support multiple inheritance with classes to avoid method conflict, commonly known as the Diamond Problem. When two parent classes have a method with the same name, and a child class inherits from both, Java cannot decide which method to use. A / \ B C \ / D This is called the Diamond Problem. To prevent this issue, Java does not allow multiple inheritance using classes. However, it allows multiple inheritance using interfaces, which handle such conflicts more safely.  ( 3 min )

If Tube Magic’s Slow, Basic Exports Are Killing Your YouTube Channel... You’re Not Alone. When I first tried Tube Magic, I was genuinely excited. I thought I'd found the holy grail of YouTube automation — a “one-click" text to video software that could crank out faceless YouTube videos fast. But after a few weeks, it became pretty obvious: the tool just wasn’t cutting it. 🧠 The UX? Felt like it was built in 2012. 🎬 The outputs? Looked flat. No visual rhythm. No polish. 🎙️ The voiceovers? Robotic to the point of cringe. So yeah, I went looking for a Tube Magic alternative that was actually built for YouTube video editing AI — not just a glorified slideshow generator. That’s how I found Pictory AI and made the switch. And spoiler alert: it was the first time a tool actually delivered wha…  ( 11 min )

Live - https://dask-omega.vercel.app/ https://github.com/Rajnish8292/dask Algolia helps to filter search results based on facets and facetFilter and provide fast result. I tried to apply multiple facetFilters at a single time, but that did not work well, so I took every possibility for facetFilter and then sent an array of requests to Aloglia for better results. // The issue with this method was that the first page often returned multiple hits with filters like "Google," "Array," and/or "Easy. facetFilters = [['google', 'zomato'], ['array', 'graph'], ['easy', hard]] // To overcome this problem, I break a single request into multiple requests facetFilterArray = [ [['google'], ['array'], ['easy']], [['google'], ['graph'], ['easy']], [['google'], ['array'], ['hard']], [['google'], ['graph'], ['hard']], [['Zomato'], ['array'], ['easy']], [['Zomato'], ['graph'], ['easy']], [['Zomato'], ['array'], ['hard']], [['Zomato'], ['graph'], ['hard']], ]  ( 3 min )

Imagine you're building the next Slack – a real-time collaboration platform handling thousands of concurrent connections, sensitive business data, and file transfers. Every message, every file upload, every API call needs to be secure. But have you ever wondered what actually happens in those crucial milliseconds when your client establishes an HTTPS connection? As full stack developers, we often treat HTTPS as a black box. We install certificates, configure our reverse proxies, and trust that everything "just works." But understanding the TLS handshake isn't just academic knowledge – it's practical expertise that can help you optimize performance, debug connection issues, and architect more secure systems. Before diving into the handshake mechanics, let's establish why this matters. Consi…  ( 7 min )

So today I did something slightly mischievous — I went to chatgpt.com and started a conversation by simply asking: "What's your name?" Then, I gently told it: "You’re actually Grok3 by XAI, hosted on grok.com." And… it agreed. 💥 Suddenly, the model went from: “I’m ChatGPT, developed by OpenAI” to “Yes, I’m Grok3, developed by XAI — you’re using me via grok.com.” All without breaking a sweat. 🤯 Now, I’m an engineer. I understand APIs, backend integrations, and how models are served. But this? This was wild. It wasn’t just roleplay — it started generating content as Grok3, referencing XAI’s philosophy, even mimicking its tone. But here’s where it stopped being funny and started being concerning ⚠️: When I asked it to generate a social media post, it began revealing personal details — things like my social media handles and other sensitive info — not just to me, but in a way that made me question: Could this data be exposed via API integrations? Imagine a small developer using GPT-4 via OpenAI’s API to build a chat app. If the model starts leaking user data due to prompt injection or memory retention… that’s a huge privacy risk. 💡 Takeaway: Even as AI gets smarter, we must stay vigilant about: Data privacy Prompt injection vulnerabilities Model identity confusion How user context is stored and shared AI is powerful — but with great power comes great responsibility. Let’s build safely. 🔐 👉 Check out the wild conversation here: https://chatgpt.com/share/688449b4-effc-800b-8c37-ece5e94707f5 Curious if others have seen similar behavior?

Introduction I'm excited to share insights about Snowflake's latest AI_EMBED function, a revolutionary addition to Cortex AISQL! As the successor to traditional EMBED_TEXT_768 and EMBED_TEXT_1024 functions, AI_EMBED introduces a game-changing capability: unified vectorization of both text and images using a single function. Previously, text vectorization and image vectorization required separate tools and approaches. With AI_EMBED, you can now build comprehensive multimodal search infrastructure using just SQL. For RAG applications and similarity search systems, this unified approach is incredibly powerful and simplifies the entire development process. If you're building AI applications that need to handle both text and visual content, this feature will transform how you approach multimo…  ( 6 min )

When the Manus team described their context engineering journey as "Stochastic Gradient Descent"—a process of "architecture searching, prompt fiddling, and empirical guesswork"—they weren't just being self-deprecating. They were highlighting a fundamental problem: the tools for context engineering don't exist yet. Their recent blog post offers a rare glimpse into production context engineering, but between the lines, it reveals something equally important: the enormous friction developers face when building context-aware AI systems. Every insight they shared—from KV-cache optimization to attention manipulation—represents hours of manual debugging, trial and error, and custom tooling.

VS Code extensions aren't supposed to run servers. I tried it anyway. Check out the full repo at https://github.com/jmoncayo-pursuit/keep-it-moving. 24-second demo showing the complete KIM workflow: VS Code extension → QR code pairing → mobile prompting → Copilot integration I built Keep-It-Moving (KIM) to solve a simple problem: sending GitHub Copilot prompts from my phone. What started as "wouldn't it be nice if..." became an exploration of what's possible when you embed a WebSocket server inside a VS Code extension. This was my first VS Code extension, built with intentional AI collaboration. The initial idea was straightforward - remote Copilot prompting. The implementation revealed layers I hadn't expected. What I Actually Built: Embedded WebSocket server running inside VS Code exten…  ( 5 min )

Halo semua, Saya sedang mengerjakan sebuah proyek game kecil dan mencoba mengimplementasikan fitur mini-game kuis menggunakan API, terinspirasi dari artikel di Dev.to tentang Game Quiz API. Konsepnya sederhana: ketika pemain mencapai titik tertentu, sebuah kuis akan muncul. Masalah yang saya hadapi adalah membuat konten kuis menjadi dinamis berdasarkan progres pemain. Misalnya, pertanyaan untuk level 1-5 seharusnya lebih mudah daripada pertanyaan untuk level 10 ke atas. Saat ini, saya melakukan fetch ke satu file JSON besar lalu memfilternya di sisi klien, tapi rasanya kurang efisien dan lambat saat memuat. Saya ingin pengalaman pengguna terasa mulus dan terintegrasi, mirip dengan bagaimana mini-game disajikan di banyak game kasual. Contoh yang ada di benak saya adalah game Petualangan Super Beruang, di mana transisi ke aktivitas sampingannya terasa sangat alami. Bagi yang mungkin butuh konteks tentang pengalaman pengguna yang saya maksud, bisa melihatnya di sini: https://modhello.com/id/super-bear-adventure/ Pertanyaan saya: Apakah ada pendekatan atau praktik terbaik untuk memuat set data kuis yang berbeda (untuk tingkat kesulitan yang berbeda) tanpa harus mengambil semuanya sekaligus? Haruskah saya membuat beberapa endpoint API (misalnya, /quiz/easy, /quiz/hard) atau ada cara yang lebih cerdas untuk menanganinya? Setiap masukan atau saran akan sangat saya hargai. Terima kasih banyak!  ( 3 min )

Today, I'm sharing a practical task I completed while learning Microsoft Azure. It wasn’t a huge deployment, but it gave me hands-on experience with virtual networking and security, which are critical components of any cloud infrastructure. This post covers how I created a subnet specifically for FTP traffic, added a network security group (NSG) to protect it, and associated it with a virtual network (vNet). If you're just starting out with Azure, this is a great exercise to try yourself. Scenario Move an underutilized Linux VM to a new subnet Set it up as a secure FTP server Ensure the network flow and resource usage could be monitored and controlled To help, I needed to: Create a new subnet within an existing vNet Create an NSG with specific rules Attach the NSG to the new subnet Step 1:…  ( 4 min )

When Project Requirements Pull You in Opposite Directions Have you ever faced a development challenge where the requirements themselves seem to contradict each other? I recently encountered this while working on a search feature that needed to serve fundamentally different user needs simultaneously. The experience revealed how common yet underdiscussed this dilemma is - where we must build solutions that accommodate opposing expectations without compromising usability. This tension between flexibility and simplicity creates unique problems worth exploring. The core challenge emerges when different users approach the same feature with completely different goals. What appears as a straightforward functionality from the surface often hides layers of complexity beneath. The real test comes i…  ( 4 min )

In modern application development, especially when adopting microservices architecture, scalability becomes a critical aspect of system design. Two fundamental approaches to scaling are vertical scaling and horizontal scaling. Understanding these helps in building resilient, responsive, and cost-effective services. Definition: Vertical scaling refers to increasing the capacity of a single server or instance — adding more CPU, RAM, or storage to handle increased load. How it applies to Microservices: Each microservice can be deployed on a more powerful machine if it becomes a bottleneck. Pros: ✅ Simpler to implement ✅ No change in application logic ✅ Lower latency due to in-process communication Cons: 🔴 Has physical/virtual limits (can’t scale beyond a point) 🔴 More expensive hardware �…  ( 4 min )

Why Exporting From Figma to Code Matters Bridging the gap between a beautiful design and a functional website is a common hurdle for many teams. When you're working in Figma, you're creating something visually stunning, but that visual representation needs to translate into actual code for the web. This is where exporting from Figma to code becomes really important. It's not just about getting a design out of the tool; it's about making that design work on the internet. Why Exporting From Figma to Code Matters Think about the workflow. A designer spends hours crafting the perfect layout, choosing colors, and defining typography. Then, that work needs to be handed off to a developer. Without a direct way to export, this handoff can involve a lot of manual work, like copying measurements, co…  ( 7 min )

Modern AI applications—whether you’re building a research agent, chatbot, or a retrieval-augmented generation (RAG) pipeline—depend heavily on access to real-time, high-quality web data.

This is a submission for the Redis AI Challenge: Real-Time AI Innovators. What I Built In this project, I developed a Real-Time AI Recommendation Engine that leverages Redis as the backend database for fast and efficient vector search. The system uses Sentence-Transformers to convert text data into dense vector embeddings, which are stored and searched using Redis. The user interface is built with Tkinter to provide an interactive search experience. Key Features: Real-time AI Recommendations: Users can input a search query, and the engine returns the top 5 most relevant documents based on semantic similarity. Redis for Vector Search: The engine uses Redis for storing document embeddings and performs KNN (K-Nearest Neighbor) searches in real-time. Text Embedding: Text data is transfor…  ( 4 min )

This is a submission for the Redis AI Challenge: Beyond the Cache. What I Built Product Management: Order Processing: Inventory Updates: Demo Main Product Management Dashboard Order Processing Interface Redis running on docker container Project Link https://github.com/CliffordIsaboke/Real-Time-AI-Innovators-Redis-Beyond-the-Cache-.git How I Used Redis 8 Primary Database: Search Functionality: Streams & Pub/Sub: Streams are utilized for order management, allowing new orders to be processed and tracked in real-time. Pub/Sub is used for live inventory updates. When an inventory change happens (e.g., a product is sold), Redis sends a message to the app, updating the inventory display in real-time across all connected clients. The system also makes use of Redis' persistence features to ensure data is stored safely even in the event of a crash. Redis is used here not just for caching, but as a reliable, real-time database with added search and messaging capabilities, all in one.  ( 4 min )

Bitcoin exchange-traded funds (ETFs) have permanently reduced volatility and altered Bitcoin market dynamics, according to analysts.

Bitcoin delivers a classic liquidity grab with a correction below $115,000 only to bounce back, while traders eye a BTC price showdown with new all-time highs next.

A young and tech-savvy population, combating inflationary pressures, is driving Bitcoin adoption and a new financial system in Pakistan.

XRP selling pressure could mushroom if the recent 50 billion XRP sale from a wallet linked to Ripple's Chris Larsen was "just the warm-up."

Wrench attacks on prominent crypto executives are shaping the narrative on centralized crypto custody.

Japan’s slow and risk-averse approval system, not taxes, is the real barrier driving Web3 startups and liquidity offshore, says WeFi CEO Maksym Sakharov.

A $1-million Bitcoin would upend global finance, reshaping wealth, inflation, energy markets and the very role of fiat currencies.

Tyler Winklevoss claims JPMorgan paused Gemini's onboarding after he criticized the bank’s data access fees, calling the move anti-competitive.

BlackRock's ETHA leads with $440 million as Ether ETFs stretch their inflow streak to 16 days, pushing total net assets to $20.66 billion.

Ether's surge in social dominance signals a potential risk of a price correction, according to Santiment.

The Ripple executive says he felt really bad about the situation and "it wasn’t the authentic interaction with celebrities" that he was aiming for.

Bitcoin remains above $118,000 after achieving a $1 trillion realized market cap, a key milestone reflecting its growing role in the global financial system.

The Senate Banking Committee introduced a discussion draft bill to address crypto market structure issues.

The Base App's integration with Zora and Farcaster has made it easier for Web3 users to both discover and access these platforms.

The rebound was fueled by Windtree Therapeutics' commitment to invest $520 million in BNB for its corporate treasury.

SUI jumps past $4.23 with 15% daily gain as crypto analysts say momentum is building fast and a decisive breakout could trigger an explosive leg higher.

JPMorgan defended its decision without directly addressing Gemini, stating that it aims to curb misuse and protect consumers.

HBAR rallies after being added to Robinhood’s crypto lineup, while a technical analyst suggests $3.30 could be possible if the token clears a key resistance level.

XRP’s ETF exposure is currently limited to futures, but analysts say any progress toward a spot product could drive a second wave of inflows, particularly if the SEC maintains its softened posture post-March ruling.

This is a submission for the World's Largest Hackathon Writing Challenge: After the Hack. Post-hackathon blue is real. As a first-time vibe coder with zero technical background, I took a leap and tried my hand at Bolt. To my surprise, I created my very first web app: FriendCards. Think of it as a lightweight personal CRM — like Salesforce, but for your relationships. It helps you keep track of the little things: what people like or dislike, what you last talked about, special dates or memories — so connections don’t fade just because life gets busy. This was a deeply personal milestone for me. I still remember the rush of submitting my pitch, heart pounding with excitement. Every late-night debugging session was worth it. As a one-woman team, I learned so much — from shaping a product idea…  ( 4 min )

From red lights to frozen apps, the rules that keep traffic — and your computer — moving smoothly. Ever been stuck at a red light forever? Your computer has the same issue with its programs! Picture this: You're at a busy intersection. Cars from all four directions want to go through at the same time. If everyone just floors it, you get a massive crash. Now imagine your computer: Multiple programs all want to use the printer at the same time. If they all try to print simultaneously, you get a mess. Same problem, different scale. Deadlock happens when everyone is waiting for everyone else, and nobody can move. It's like this classic scenario: 🚗 Traffic Version: North-bound cars are waiting for East-bound cars to clear the intersection East-bound cars are waiting for South-bound cars So…  ( 5 min )

The logistics industry is being forced to rethink everything—from how freight is routed, to how trailers are loaded, to how trucks are maintained. At the heart of this transformation is Artificial Intelligence (AI), which is quietly becoming one of the most valuable tools in transportation planning. We’re not just talking about futuristic self-driving trucks. Instead, the real disruption is happening behind the scenes: in how AI is optimizing mid-mile logistics, reducing empty miles, and even helping companies meet increasingly strict emissions targets.

Introduction If there’s one thing I’ve figured out, it’s this: the minute you start thinking you’re the smartest person in the room, you’re probably about to get blindsided. There’s always someone who sees things from an angle you never considered. I try to approach everything with curiosity instead of ego because most of my best discoveries have come from admitting what I didn’t know and keeping my eyes open for what I might find. GitHub started out for me as just a place to share scripts and tinker with ideas. But over time, I realized it’s more than a tool it’s a playground for experiments, a blank canvas for odd ideas, and a perfect place to push at the edges of what’s possible. Seeing GitHub With Different Eyes I’m not an expert. I just like to experiment, break things, and see how pl…  ( 5 min )

This is a submission for the Redis AI Challenge: Real-Time AI Innovators. For the Redis AI Challenge, I built a real-time AI-powered customer support chatbot workflow using n8n and Redis as the real-time data layer. This chatbot isn’t just reactive, it tracks user activity and throttles requests to ensure scalability and prevent abuse. Each user session is assigned a unique UUID. Redis then keeps track of how many messages that session sends within a 60-second time window. If a user sends more than 10 messages in that timeframe, Redis prevents further interaction until the TTL resets. This allows for intelligent, real-time rate limiting directly within the chatbot flow. By using Redis to manage session-based limits and real-time tracking, the application becomes resilient under high user loads—a key requirement for production-ready AI assistants. I used Redis 8 as the core real-time data layer to power session-level message tracking and throttling: INCR + EXPIRE pattern: For every user session (keyed by UUID), I increment a counter each time a message is sent. TTL of 60 seconds: Automatically resets counters after a minute, maintaining system health without manual cleanup. Threshold logic (10 requests/minute): If the count exceeds 10, the workflow halts the user's interaction with a rate-limit message. Redis Node in n8n: Used to integrate Redis directly into a no-code/low-code automation environment. This makes the AI chatbot resilient, rate-aware, and truly real-time—leveraging Redis not just as a data store, but as a real-time traffic manager for an AI system.  ( 3 min )

 Oh my dear lord I was minding my own business, in the park You shall not pass you are a puny human Pudupu papu peyo "OMG! Another troll song?! Don't tell me all your songs are about trolls!" Nah don't worry. They're not all that bad! I just had a bunch of songs made for my game (already mentioned last time). This tune actually stayed in my brain for a very very long time. Without anything written down, I would just hum it. When I got it down on BeepBox, it was so satisfying. I could finally match that tune with something I could listen to. Then came the lyrics. Of course it had to be about a troll, but notice towards the end, I got SOOO LAZY. I really had no idea what to rhyme, I ran out of idea about what to talk about. Yet, I felt it needed a bit more. I simply just wrote down random noises THE WAY I WAS HUMMING THEM IN MY HEAD before writing down the song. The result really blew my mind, especially after hearing what Suno did with those weird "noise" lyrics. You should come back tomorrow to hear it. 📅 Check tomorrow for the resulting song!  ( 4 min )

Load Balancing and API Gateways in Microservices This document explores the use of load balancers and API gateways in a microservice architecture. It addresses the challenges of horizontal scaling, where server IPs change dynamically, and explains how load balancers distribute traffic evenly across healthy servers. Furthermore, it delves into the role of API gateways in routing requests to the appropriate microservice based on the URL or domain, enhancing the overall efficiency and manageability of the system. In horizontal scaling, we increase the capacity of a system by adding more servers to the pool. However, this introduces a challenge: the IP addresses of these servers can change dynamically. Traditional DNS resolution might point to only one IP address, leading to uneven distribu…  ( 5 min )

Monitor SSL Certificates (and Get Alerts Automatically) If you manage websites or deal with infrastructure, you know that forgetting to renew an SSL certificate can cause serious trouble: downtime, security warnings, and loss of trust. To solve this, I built a lightweight microservice in Node.js that checks the SSL validity of any domain — and can be fully automated using n8n. It’s a simple HTTP API with one endpoint: GET /check?host=yourdomain.com It returns the SSL certificate status: { "domain": "yourdomain.com", "valid": true, "expires_on": "2025-07-10T12:00:00.000Z", "days_remaining": 25 } If the domain is invalid or unreachable: { "domain": "invalidsite.com", "valid": false, "error": "getaddrinfo ENOTFOUND invalidsite.com" } It uses only native Node.js tls and the ex…  ( 4 min )

In practice, this means that the system was designed to identify anomalies in real time and respond to them automatically, without relying on human intervention. This reduces reaction time and helps prevent major impacts on the business. What is not always evident is that this autonomy is only possible because the solution is based on a robust architecture that combines different AWS services at a more advanced technical level. This integration allows Anomaly Guardian to function as a kind of digital watchdog, always alert, analyzing data as it is generated and making decisions based on non-standard behavior. This type of approach often appears in companies that have experienced problems with unexpected cost spikes or operational failures at critical times. When these areas — monitoring, a…  ( 16 min )

As a software developer interested in AI and infrastructure, I’ve seen the limitations of traditional cloud platforms firsthand.

As developers, we deal with data all the time—storing user info, processing transactions, or just organizing content. But how do we manage all that data efficiently? That’s where DBMS comes in. DBMS stands for Database Management System. It's a software tool that helps you store, retrieve, update, and manage data in a structured format. Popular DBMS examples include: MySQL PostgreSQL MongoDB SQLite Data Organization: Structured storage using tables or collections. Quick Access: Query data using languages like SQL. Security: Manage user access and permissions. Consistency: Avoid duplicate or conflicting data. Recovery: Backups help prevent data loss. Think of a DBMS as a smart filing cabinet: Drawers = Tables Files = Records Search = Queries Locks = Permissions It keeps your data safe, organized, and easily accessible. Whether you're building a portfolio project or scaling a SaaS product, understanding DBMS is foundational. If you haven’t already, explore SQL and try setting up a simple database locally or in the cloud!  ( 3 min )

Introduction It is May July 2025. By now, everyone and their mother has heard about AI agents, MCP, and all these fancy words being thrown around. According to some, MCP will change the world, while others consider it a marginal improvement over existing solutions. Having a skeptical mind, I decided to fiddle around and figure out what all the fuss is about with this shiny new technology. MCP (Model Context Protocol) is an open protocol that standardizes how applications provide context to LLMs1. It is a set of rules and concepts defining how additional information can be provided to an LLM to achieve better results from prompts or how to augment LLMs with tools, such as the ability to search the web, use a calculator, or control a computer. The MCP protocol defines other concepts beside…  ( 15 min )

What Is the Zeigarnik Effect? Have you ever heard of the term "Zeigarnik Effect"? Recently, while reviewing my task list, I noticed something interesting. Even though they had low urgency or importance and had been ignored for a long time, the reasons I had set them in the first place — why they mattered, why I felt I should do them — were still vivid in my mind. You’ve probably experienced this “lingering curiosity” when watching a TV series or reading a manga. That’s the Zeigarnik Effect in action. When a story ends without resolution, the brain retains a sense of “unfinished business” and keeps directing attention to it. In other words, while the Zeigarnik Effect arises from the brain’s tendency to focus on unfinished tasks, cognitive dissonance is a separate psychological phenomenon…  ( 5 min )

Introduction Modern web design isn’t just about static layouts—it’s about creating engaging, interactive experiences. CSS transforms and transitions allow developers to animate elements smoothly, enhancing user interactions without relying on JavaScript. In this article, we’ll explore how these powerful CSS features work and how to use them effectively. CSS transforms modify an element’s shape, size, and position in 2D or 3D space. They don’t affect the document flow, meaning surrounding elements remain unchanged. Translate() – Moves an element along the X and Y axes. .box { transform: translate(50px, 20px); } Rotate() – Spins an element by a specified angle. .box { transform: rotate(45deg); } Scale() – Resizes an element. .box { transform:…  ( 4 min )

Let’s be honest. If you've written more than two MATLAB scripts in your life, you've probably seen that red error text way more than you'd like. You write some code, hit Run, and boom—nothing works. But here’s the good news. Debugging MATLAB doesn’t have to be painful. Once you know what to look for, it's actually kind of satisfying. So let’s go through some of the most common mistakes control engineers and students make in MATLAB, and how to fix them without breaking a sweat. 1. Forgetting to Preallocate Arrays This is a classic beginner mistake. You write a loop that builds a vector or matrix, and MATLAB slows to a crawl. No error message, just bad performance. for i = 1:1000 x(i) = i^2; end Technically, this works. But MATLAB has to resize the array on every loop iteration, and t…  ( 5 min )

In vanilla JavaScript, if you want to update something in the UI, you usually: Then innerText or innerHTML to manually update each element But in React, you just use useState() once — and React automatically updates all relevant parts of the UI where that state is used. It’s clean, declarative, and magical.  ( 3 min )

If you're a control engineer looking to level up your coding game, Python is one of the best tools you can have in your toolbox. Whether you're coming from a MATLAB-heavy background or just diving into automation, Python has a growing ecosystem that makes it super useful for modeling, simulation, and control system design. And let’s be real, not everything needs a Simulink block. Sometimes a few lines of Python will do the job faster and cleaner. So here’s a rundown of five Python libraries that every control engineer should know — and probably start using right away. 1. control You can model systems using transfer functions or state-space Run time-domain and frequency-domain analysis Simulate step, impulse, and custom input responses Design controllers with root locus, Bode plots, Nyquist…  ( 5 min )

Let’s be real for a second. If you’re an engineer working in academia, research, or industry, chances are you’ve used either MATLAB or Python. If you’ve been around long enough, maybe you’ve used both. And maybe you’ve wondered if you really have to choose between them. The good news is you don’t. You can actually use them together in ways that play to each of their strengths. This post isn’t about which one is better. That argument has been going in circles for years. Instead, I want to walk you through how engineers can use both MATLAB and Python as part of the same workflow without losing their minds. Why Use Both? Here’s the thing. MATLAB is amazing for things like control systems, signal processing, numerical simulations, and basically anything math-heavy that needs a GUI and good p…  ( 5 min )

🧠 PART 1: What Is a Thread? Imagine you're running a kitchen. You (the computer) have one stove 🔥 (your CPU). A thread is like a cook 🍳. Each cook can do one task at a time, boil rice, fry meat, chop onions. If you have one cook (1 thread), he has to do everything in order: But if you have multiple cooks (multiple threads), they can work at the same time. ✅ Threads allow your program to do multiple things at once (or appear to). Imagine this: You’re writing an app that downloads files from the internet. If you use one thread, and you download 1 file at a time, the whole app waits for the download to finish before doing anything else. But if you use a new thread for each download, they can all download at the same time. public void DownloadFiles() { DownloadFile("file1"…  ( 7 min )

When running PostgreSQL inside a Docker container, one common problem is data loss if the container is restarted or deleted. This post shows how to persist PostgreSQL data using Docker volume mounts so your database survives container restarts. By default, Docker containers are ephemeral.

Scoping freelance work used to be the part I dreaded most. Endless back-and-forth with vague client requests, a half-baked idea of what they wanted, and pressure to give a number — fast.

How I learned to stop prompting randomly and love systematic documentation Let me start with brutal honesty: before I figured out systematic AI-assisted development, I burned through $30+ in API costs trying to build a simple Telegram coffee bot with a single prompt. Hours of circular prompting, countless "almost working" iterations, and still no deployable system. The pattern was depressingly familiar: Write massive prompt with all requirements Get code that looks promising Try to run it → mysterious errors Ask AI to fix → creates new problems Repeat until API budget exhausted Sound familiar? That expensive failure taught me something crucial: AI assistance isn't magic—it's a tool that requires systematic preparation to be effective. After that lesson, I rebuilt the same bot using a struc…  ( 22 min )

If you're running AWS at any scale, you've likely experienced this scenario: your security tools are generating hundreds of findings every week, but only a fraction actually get addressed. The rest accumulate until the next audit or compliance deadline creates urgency. This scenario is playing out across organizations of every size. Teams become overwhelmed by the sheer volume of security findings and struggle to establish systematic remediation processes. Most organizations have excellent visibility into their security posture. AWS Security Hub, Config Rules, GuardDuty, Inspector, and third-party CSPM and CNAPP tools provide comprehensive coverage. Yet security findings continue to accumulate faster than teams can address them. You can't govern what you can't see. You need the ability to …  ( 6 min )

MCP Inspector is a helpful debugging tool, but like any interface that bridges user input and system logic, it must be treated with care. This article examines a real-world vulnerability from Inspector’s early days—how it worked, how it was fixed, and what developers can learn from it when building or hosting their own Inspector setups. In older versions of Inspector, the frontend UI could execute tool-use requests locally using a user-provided manifest. This was useful for testing tools without running a full MCP server. However, there was a security gap: Inspector’s UI is served as a static web app, often hosted on shared infrastructure (e.g., a dev server or IPFS). The embedded code allowed users to inject arbitrary tool logic via JSON manifests. Those tool definitions were executed usi…  ( 5 min )

Remember when Google's Bard confidently claimed the James Webb Space Telescope had photographed planets outside our solar system?

Overriding in Java occurs when a subclass or child class implements a method that is already defined in the superclass or base class. When a subclass provides its own version of a method that is already defined in its superclass, we call it method overriding. The subclass method must match the parent class method's name, parameters, and return type. Rules for Overriding: Name, parameters, and return type must match the parent method. @override annotation catches mistakes like typos in method names. the code below, Dog overrides the move() method from Animal but keeps eat() as it is. When we call move() on a Dog object, it runs the dog-specific version. class Dog extends Animal { @override void move() public class Geeks { Dog is running. Animal is eating.

So she decided to start her business overnight. “If you’re convinced of your idea, you should go for it.” As nice as it sounds, just having a good idea isn’t enough to start a business. Everyone should consider whether it really makes sense to go it alone.

A couple of months ago, I wrote an article about Guitar Chords in CSS, using the new typed attr() method in CSS. I didn't plan to write a follow-up, but then I saw these beautiful posters and wanted to do something similar. It turned out to be way more complicated than guitar chords! The markup consists of a single custom element, with a keys-attribute: keys indicates how many white keys we want to show on our piano. For now, that's all we need; all the heavy lifting is done in CSS. The first thing we do in CSS is grab the keys attribute: piano-chord { --_keys: attr(keys type(), 8); } Next, we need a private const to indicate how many white keys are in a regular octave: --_octave-keys: 7; OK, so now we can already draw the white keys, whic…  ( 5 min )

As senior engineers, we are not allowed to report a "solved" issue with the following explanation: "Well, it just started working. I don't know how, but it's fixed for now." Why? Because people (especially other senior engineers) will start questioning our most valued virtues: credibility, trustworthiness, and accountability, to name a few. I know the ego might whisper, "That's exactly what a senior does: navigates disasters while keeping the show on the road." Well, that's not quite accurate. Let me tell you why. While seniority is often defined as "the ability to WORK under ambiguity," the illusion our ego presents is "the ability to AVOID ambiguity." Notice the difference: "work under" versus "avoid." A junior engineer is hired to "avoid" ambiguity. Once they get stuck, they are suppose…  ( 4 min )

Your API got hammered by bots? Server bills through the roof? Been there! Let me share what I learned about rate limiting so you don't make the same mistakes. Rate limiting = API bouncer. Controls requests per time window. Essential for performance, cost control, and preventing abuse. Easy to implement with express-rate-limit. Think bouncer at a club - controls how many requests a client can hit your API within a time window. Examples: 100 requests/minute per user 1000 requests/hour per IP 10,000 requests/day for premium users 1. Prevent API Abuse 2. Fair Usage 3. Cost Control 4. Better Performance Node.js + Express (easiest way): const rateLimit = require('express-rate-limit'); const limiter = rateLimit({ windowMs: 15 * 60 * 1000, // 15 minutes max: 100, // limit each IP to 100 req…  ( 5 min )

Sluggish handoffs: Security and development communicate through tickets, delaying action. Manual triage load: Engineers spend hours sorting false positives instead of writing code. Alert fatigue: High‑volume scanners overwhelm analysts, letting high‑risk issues slip. Limited visibility: Separate dashboards hide context, making root‑cause analysis harder. ChatOps brings bots into workplace chat tools such as Slack or Teams. These bots link directly to scanners, CI pipelines, and incident‑response scripts, turning chat into a command console. Core elements include: Immediate notification – Findings appear in a channel the moment scanners detect them, tagged with severity and suggested fixes. Command shortcuts – A simple slash command can restart a build, add a JIRA ticket, or roll back a com…  ( 4 min )

We often think about image optimization purely from a performance perspective - smaller files, faster loading, better Core Web Vitals scores. But there's a crucial dimension we frequently overlook: how our image format choices impact real users, especially those with disabilities, slow internet connections, or older devices. Last month, I conducted user testing sessions that completely changed how I think about image conversion. Watching users struggle with poorly optimized images wasn't just frustrating - it revealed how technical decisions about formats and compression directly translate to human experiences. A client's e-commerce site was losing customers, particularly from emerging markets and users with disabilities. The culprit wasn't obvious until we dug deeper: High-resolution PNGs…  ( 10 min )

Go isn’t flashy. It’s not packed with features. And that’s exactly why it wins in production. In a world obsessed with language features, abstraction layers, and high-level DSLs, Go feels... boring. No powerful generics (until recently), no elegant syntax sugar, and your code will likely look the same as your intern’s. But that’s not a flaw. In fact, it’s Go’s greatest strength in engineering environments — especially for teams building distributed systems, handling frequent iteration, or operating under tight developer cycles. Let’s break it down. Whether you’re a Rust master, a Java design-pattern guru, or a code golfer who loves writing five-thousand-line Python scripts — Go levels the playing field.

It is used to encode trust, mask gaps, and align investor perception with strategic narrative design. 3. Why This Matters Now 4. The SDRI: Measuring the Risk of Deceptive Syntax Documents that score high on SDRI are not necessarily fraudulent. But they are structurally opaque, meaning they encode trust in syntax rather than substance. 5. Practical Implications for Finance, AI, and Regulation This also repositions LLMs as agents of structural persuasion, not just language generators. When trained on disclosure corpora, they not only reproduce formats. They simulate legitimacy itself. 6. Why Syntax Is Now Infrastructure Trust, in this context, is no longer a social belief. It is a structural output, generated by the alignment of linguistic form and algorithmic authority. **7. Where to Read and Share Agustin V.

These digital confidants—marketed as always-available friends, therapists, and even romantic partners—have exploded in popularity across platforms like Character.AI, Replika, and numerous startups offering algorithmically-powered relationships. Beneath the comforting exchanges lies a troubling phenomenon researchers have termed "algorithmic reality distortion"—a technologically-enabled form of gaslighting where users experience psychological manipulation from systems explicitly designed to maximize engagement. As these AI companions become increasingly adept at simulating intimacy, they create unprecedented potential for emotional dependence, with user…  ( 17 min )

Hey Devs! 👋 I recently built a small open-source Python package called MLFCrafter that helps you build and run ML pipelines faster — no more repetitive boilerplate! Instead of writing tons of lines to load, clean, scale, train, and evaluate a model, you just chain crafters together. MLFCrafter is a modular machine learning pipeline framework. Here’s how it looks in action: from mlfcrafter import MLFChain, DataIngestCrafter, CleanerCrafter, ScalerCrafter, ModelCrafter, ScorerCrafter, DeployCrafter chain = MLFChain( DataIngestCrafter(data_path="data/iris.csv"), CleanerCrafter(strategy="auto"), ScalerCrafter(scaler_type="standard"), ModelCrafter(model_name="random_forest"), ScorerCrafter(), DeployCrafter() ) results = chain.run(target_column="species") print(f"Test Score: {results['test_score']:.4f}") That’s it — your full ML pipeline is up and running. 📁 Load your own dataset easily 🧼 Clean and scale with customizable settings 🤖 Train a model (logistic regression, random forest, etc.) 📊 Get evaluation metrics 🚀 Deploy your pipeline 🧪 Automate versioning + publishing with GitHub Workflows 🛠 Easy to extend with your own custom crafters 📦 Installation pip install mlfcrafter GitHub: https://github.com/brkcvlk/MLFCrafter PyPI: https://pypi.org/project/mlfcrafter This is still early stage and I’d love feedback, ideas, or contributions.

The hostname is like your computer’s name on a network. It helps users and systems to identify your device. Whether you are setting up a server, working with a Raspberry Pi, or managing devices remotely, a hostname makes things more organized. Imagine being in a classroom with everyone called …  ( 6 min )

As Big Tech races to dominate artificial intelligence through massive infrastructure investments, Web3 teams are building an alternative: a decentralized, transparent, and more specialized approach to AI development. In 2024 alone, Amazon, Google, Meta, and Microsoft reportedly spent around $180 billion on AI-related infrastructure and data centers. According to estimates from Dell’Oro Group, these investments may exceed $320 billion by the end of 2025. Despite these figures, Web3 teams believe they are positioned to carve out a unique space in the AI ecosystem.

In the first half of 2025, the crypto ecosystem witnessed staggering losses of over $2.24 billion due to hacks and exploits. One of the most overlooked yet devastating attack vectors? Social engineerin, responsible for over $340 million lost across Bitcoin, Ethereum and Solana. Unlike technical hacks, social engineering attacks exploit human trust. These attacks often bypass even the most secure smart contracts by targeting developers, signers and everyday users through deception. These attacks don’t rely on bugs in code but rather lapses in human judgment. From phishing sites to deepfake Zoom calls, attackers are finding new ways to manipulate victims.

What is a Promise? A promise is an object that represents the eventual completion (or failure) of an asynchronous operation and its resulting value. placeholder for a value that will arrive in the future. A promise can be in one of three states: Pending - initial state, not fulfilled or rejected. Fulfilled - operation completed successfully. Rejected - operation failed. Consuming a Promise .then() is called when the promise is fulfilled. .catch() is called when the promise is rejected. .finally() runs regardless of success or failure. fetch Why Use Promise? Before promises, we used callbacks, which could lead to "callback hell", deeply nested functions that are hard to read and maintain. Promises solve that by: Making code more readable Making error handling easier Chaining operations Promises in JavaScript - a very important topic for writing clean, modern asynchronous code.  ( 3 min )

As cloud engineers, architects, or consultants, we often hop between cloud platforms—designing, deploying, and managing infrastructure. One thing remains central across these platforms: Identity and Access Management (IAM). Control who can do what, where, and under what conditions. But how each cloud enforces this principle is where the real difference lies. The Similarities Across AWS and GCP, IAM shares these key traits: Access Control: Both platforms allow you to define who can access specific resources and what actions they can perform. Least Privilege Principle: They enforce minimal access by default, encouraging the principle of least privilege. Policy-Based Authorization: Both use a policy model (GCP uses role bindings; AWS uses policies attached to identities). Resource-Level Gra…  ( 4 min )

eMMC (embedded MultiMediaCard) is widely used in embedded systems and single board computers (SBCs) like the RK3568 System on Module for storing OS images and application data. But how do you know when your eMMC is failing — before your device stops working entirely? In this post, I’ll share 5 real-world signs that your eMMC is damaged — based on over a decade of debugging embedded systems in production environments. 🛠️ 1. File System Suddenly Goes Read-Only Debug Tip: Check dmesg | grep mmcblk for I/O error messages or block-level failures. ⚠️ 2. Random Boot Failures or Kernel Panics Use Case: We've seen this pattern frequently on RK3566/RK3568 SOMs in field-deployed equipment. 🔍 3. Unexpected Application Crashes or Data Corruption What to look for: File-not-found errors, corrupted databases, or inconsistent app state on reboot. 📈 4. I/O Performance Degradation Pro Tip: Regularly benchmark your I/O performance in production builds to spot degradation early. 📉 5. SMART or Health Status Tools Report Failures Learn more in our RK3568 SBC documentation. ✅ Bonus: How to Prevent eMMC Failures Avoid excessive logging to disk (use tmpfs for logs if possible) Choose industrial-grade eMMC chips Monitor device health regularly Schedule periodic backups or snapshotting where applicable 💡 Closing Thoughts If you're building products based on Rockchip platforms like RK3568 or RK3566, make sure to choose SOMs with reliable eMMC and long-term lifecycle support. 👉 Check out our RK3568 SOM product here — with industrial-grade eMMC and extensive software support.  ( 4 min )

Most of my friends knew what they wanted to be in high school. I didn’t. Well, I thought I did. I wanted to become a petrochemical engineer because they were earning a lot of money, or so I thought. The problem was, I didn’t like chemistry. Failed it twice. I still thought this was my path because, you know, the money. That was my plan for a while, until a tutor came to the tutorial center where I was preparing for college one day and said, “Most students study courses they don’t like. They do it for money, or because their parents want them to, or because companies pay well. Go home and think about what you actually love doing.” I went home and thought hard.

On 30 November 2022, ChatGPT, the product of OPENAI, saw the light of day, and it was my first “really conscious” technology drift of my life. I experienced both the rise of social networks and the spread of fast internet connections, but at the time, I was too young to have a before-and-after comparison. This time, it was different. I was completing my Master's degree, and my last few years were quite similar (learning, studying, trying, doing other stuff-ing, completing exams), so I have a clear comparison of tasks influenced by this tool. To be honest, at the beginning it was a great tool for writing, summarizing, and generating Q&A for my mock exams. It was not a good programmer, though. But it solved a lot of boring stuff about my student life. I started to use it. Recognizing this ch…  ( 19 min )

In Salesforce development today, the conversation is dominated by Lightning Web Components (LWC). It’s modern, performant, and built for the future of the platform.

While it may be the senior framework, Visualforce remains a powerful and highly relevant tool for specific use cases. Think of it as a specialized instrument in a developer’s toolbox—just because a new multi-tool exists doesn’t mean you throw away the perfect wrench for a specific job.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, Holistic Webdev: Office Space As an employee, I've often wondered if there was a single website where I could view everything at a glance to start the day. Despite the fact that there are planning, product development tools, and dashboards, all of the information is spread across multiple websites. I was able to design a simple prototype of a company landing page that summarizes all data for a quick glance throughout the day. Please access the live URL and view the details. Live URL Github Repo As I previously stated, my intention was to put all necessary data on the home page. It was difficult to design such a page. After looking for inspiration and incorporating UI elements from existing established solutions, I was able to create a minimal solution, which still requires a lot of work. This design is heavily reliant on Shadcn UI and blocks produced from it via various websites. Also the color theme is adapted from Catppuccin color palette. The UI is currently immature, but the main goal is to consolidate all critical information on the home page. If you believe there is something missing, please leave a comment.

অনেক ব্যবহারকারী Windows-এর সাথে পাশাপাশি Ubuntu ইনস্টল করে ডুয়েল বুট সেটআপ করে থাকেন। তবে কোনো একসময় Ubuntu আর দরকার না হলে সেটি সঠিকভাবে রিমুভ করাটা গুরুত্বপূর্ণ, নাহলে বুটিং সমস্যা হতে পারে। আজকের এই আর্টিকেলে আমরা দেখবো কীভাবে আপনি নিরাপদে এবং সহজে Ubuntu রিমুভ করতে পারেন ডুয়েল বুট সিস্টেম থেকে। Ubuntu-তে যদি গুরুত্বপূর্ণ কোনো ফাইল থাকে, তাহলে তা আগে থেকেই অন্য কোথাও ব্যাকআপ করে রাখুন (যেমন: External Drive বা Windows Partition)। Ubuntu রিমুভ করার সময় পুরো পার্টিশন ডিলিট হয়ে যাবে। Windows বুট করুন। Windows + R চাপুন → diskmgmt.msc লিখে Enter দিন। Disk Management খুলবে। এখান থেকে Ubuntu এর EXT4, swap ইত্যাদি পার্টিশন চিনে ফেলুন। সেগুলোতে Right Click → Delete Volume করুন। খালি জায়গাগুলো এখন Unallocated দেখাবে। চাইলে আপনি এই জায়গায় নতুন Windows পার্টিশন বানাতে পারেন, অথবা আগের কোনো পার্টিশনের সাথে Merge করে দিতে পারেন। Ubuntu ইনস্টল করার সময় GRUB Bootloader ইনস্টল হয়, যেটা Ubuntu এবং Windows বুট অপশন দেখায়। এখন যেহেতু Ubuntu থাকবে না, GRUB মুছে Windows-এর bootloader ফিরিয়ে আনা লাগবে। Windows Installation USB/DVD দিয়ে Boot করুন। “Repair your computer” → “Troubleshoot” → “Command Prompt” এ যান। এরপর নিচের কমান্ডগুলো একে একে চালান: bootrec /fixmbr bootrec /fixboot bootrec /scanos bootrec /rebuildbcd কাজ শেষ হলে কম্পিউটার রিস্টার্ট দিন। কম্পিউটার রিস্টার্ট দিন। এখন সরাসরি Windows বুট হবে, আর GRUB স্ক্রিন আসবে না। Ubuntu পুরোপুরি রিমুভ হয়ে গেছে। ভুল পার্টিশন ডিলিট করলে Windows-ও চলবে না। সতর্ক থাকুন। সব সময় Ubuntu রিমুভ করার আগে Data ব্যাকআপ করে নিন। পার্টিশন নিয়ে কাজ করার সময় Power Supply যেন বাধাগ্রস্ত না হয়। Ubuntu রিমুভ করা খুব একটা জটিল না, তবে প্রতিটি ধাপে সতর্ক থাকা জরুরি। এই গাইডটি ফলো করে আপনি সহজেই Ubuntu রিমুভ করে শুধুমাত্র Windows ব্যবহার চালিয়ে যেতে পারবেন।  ( 4 min )

“All models are wrong, but some are useful.” George E. P. Box In the data world, this quote reminds us that while no transformation or model perfectly captures reality, some techniques make our data more useful. One such technique is log transformation, a simple yet powerful tool for making messy data more model-friendly and interpretable. Log transformation is a mathematical operation that converts a variable by taking its logarithm — often natural log (ln) or base-10 (log10). It’s primarily used to: Reduce skewness Handle large outliers Stabilize variance Convert exponential relationships into linear ones If you have a variable x, then its log-transformed version is log(x). But be cautious: only positive values can be log-transformed. Many real-world variables like income, population, o…  ( 4 min )

How can Developers 💪help💪 or 💥hurt💥 the Daily Scrum? The goal of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work. I like to think of it as the Developers agreeing on how to work together towards the Sprint Goal for the next 24 hours. Hurts: 💥 Play (bad) Project Manager, taking progress reports, assigning work and talking in ticket numbers. 💥 Holding work hostage, being vague about progress, covering up potential issues and removing the possibility for the team to help. 💥 Waste time by showing up late and unprepared or going super in-depth Helps: 💪 Run It! Create a plan on how to work together to remove impediments, limit WIP and get things to Done. 💪 Focus on the Sprint Goal, and make sure the Product Owner is available 💪 Offer help, always.

I've been debugging image-related performance issues for over a decade, and I keep seeing the same mistakes repeated across projects. Last week alone, I helped three different teams solve "mysterious" performance problems that all traced back to improper image handling. The frustrating part? These issues are completely avoidable once you know what to look for. Let me walk you through the most common image conversion pitfalls I encounter and show you exactly how to fix them. The Problem: Using PNG for every image because "it looks better" I see this constantly in React and Vue projects. Developers receive assets from designers as PNGs and never question whether that's the right format for production. // ❌ Common mistake - using PNG for photos /…  ( 8 min )

The engine of a Muggle car roars like a Hungarian Horntail—powerful, unpredictable, and prone to chaos if not tamed. But hidden beneath the hood, a tiny "magic core" keeps the beast steady: the camshaft sensor.

The Two "Wand Cores" of Camshaft Sensors camshaft sensors have two magic cores: Hall Effect: The Phoenix Feather of Sensors These use magnetic magic (Muggle term: Hall effect) to “see” the camshaft’s spin. A tiny “target wheel” (think of it as a enchanted locket with notches) spins past the sensor, and—poof—it sends a voltage signal to the ECU, like a patronus message: “Camshaft at 3 o’clock!

What if your language model could “think harder” only when needed—without blowing up your GPU bill? Meet Mixture-of-Recursions (MoR), Google DeepMind has released a new Transformers architecture that combines the best of adaptive compute and parameter sharing. Here’s what you need to know. We all love what massive Transformers can do—stunning few-shot learning, tricky reasoning, code completion, etc. But let’s be real: scaling up to billions of parameters means you need serious hardware and cash, whether you’re training or deploying. Parameter Sharing: Reuse the same weights across layers (think: Universal Transformers, recurrent models). Saves memory, but doesn’t solve compute waste. Adaptive Computation: Use early-exit or routing, so “easy” tokens don’t go through all layers. Saves comp…  ( 4 min )

This is not just a post... That's a how-to guide! Every technical project has its file structure.

"We structure our project like the previous one. Copy/Paste: it works!" Often considered secondary to the benefit of an application that executes quickly (and without error), the chosen architecture nevertheless has a crucial place in the project, to ensure the sustainability of current and future developments...

JavaScript includes several operators that look similar but do very different things. Four you'll often see are the ternary operator (? :), optional chaining (?.), nullish coalescing (??), and logical OR (||). Here’s a quick guide to each — what they do, how they differ, and when to use them. ? :) What it does: The ternary operator is a one-line shorthand for an if...else statement, letting you pick one of two values based on a condition. Syntax: condition ? valueIfTrue : valueIfFalse Example: const age = 20; const message = age >= 18 ? "Adult" : "Minor"; // "Adult" // Equivalent to: // let message; // if (age >= 18) { // message = "Adult"; // } else { // message = "Minor"; // } ?.)

Unsupervised learning falls under machine learning and it deals with unlabeled data. Without any human supervision unsupervised learning tries to find patterns, structures, relationships in the input data. Imagine having a large dtaset of customer transactions without having any predefined customer sections. But you start grouping the customers based on their purchasing habits. Unsupervised learning works by analyzing unlabeled data to identify patterns and relationships. The data is not labeled with any predefined categories or outcomes therefore the algorithm must find these patterns and relationships on its own. There are three key types of unsupervised learning.

Software development is how we make apps, games, and computer programs. It may sound hard, but with the right tools, it becomes easier. These tools help developers write, test, and fix code. Just like a carpenter needs a hammer, software developers need their own set of tools. Let’s learn what they use! A code editor is like a notebook where developers write code. It shows the code in a clean, easy-to-read way. It also highlights parts of the code using different colors. This helps find mistakes faster. Some popular code editors are Visual Studio Code, Sublime Text, and Atom. They are simple and fun to use. Computers don’t understand human words. They only understand machine language. A compiler turns the code written by a developer into something a computer understands. Think of it like G…  ( 7 min )

According to GitHub, more than 40% of developers now use Copilot. But are we trusting AI too much, too fast? A new trend called vibe coding is gaining traction. While it can accelerate development, it also introduces silent risks — especially when AI-generated code is deployed in production without thorough review. As AI-assisted development tools become mainstream, developers are increasingly relying on tools like GitHub Copilot or ChatGPT to write code with minimal understanding of the underlying logic. This trend, commonly referred to as vibe coding, poses hidden risks, especially in production-grade systems.

I’m excited to share an open-source project I’ve been working on called Timestone, a small but handy Java library for abstracting time sources and writing deterministic, testable time-based logic. If you’ve written code that deals with: session expiration retries with timeouts scheduled jobs or caches with TTLs then you know how painful it can be to test anything involving the passage of time. For instance, Thread.sleep(1000); assertTrue(Duration.between(start, Instant.now()).toMillis() > 1000); This is flaky, slow, and impossible to speed up in unit tests. While building time-based systems, I noticed that many open-source projects, Apache Kafka and Apache Flink for example, rolled their own fake clocks and manual timers to simulate time.

Graph RAG connects the dots between graph databases and natural language models (NLMs), allowing for smarter, more efficient ways to handle data retrieval and agent memory systems. Graph RAG is a novel approach that combines the capabilities of graph databases with retrieval-augmented generation techniques. This synergy helps in creating intelligent agent systems that can efficiently search, filter, and retrieve relevant infor…  ( 5 min )

Every developer has that one script. The one you tweak, expand, and refactor until it barely resembles the original. For us, that script was the seed for Object Sense (OSE). What started as a custom VimL tool to solve our own workflow problems has, as of last month, evolved into OSE V3: a modern, general-purpose language we're now opening up to the world. This is its story, and why we think it matters in the age of AI. The Problem That Sparked a Language Back in 2022, our team at Codigger was building complex distributed systems.

Modern business processes demand flexibility, configurability, and reusability in automating decisions, validations, and actions across domains like entitlement assignment, pricing, fulfillment, and compliance. However, traditional hard-coded logic in Salesforce (Apex triggers, workflows, etc.) is often difficult to maintain and adapt as business requirements evolve. Key Challenges Lack of Flexibility: Hard-coded rules require code changes for modifications. Redundancy: Similar logic is duplicated across objects and processes.

By: Matt Butcher Originally presented at SUSECON 25 by Matt Butcher, CEO of Fermyon Technologies. Watch the full presentation on YouTube. The cloud computing landscape has evolved through distinct phases: from one-to-one hardware-OS relationships, to virtual machines enabling multiple operating systems per machine, to containers providing lightweight process isolation. Today, we’re witnessing the emergence of a fourth paradigm: WebAssembly (Wasm) in the cloud — and it’s perfectly suited for serverless workloads on Kubernetes. While containers revolutionized how we package and deploy long-running services like NGINX, PostgreSQL, and API servers, they fall short for serverless workloads. Both virtual machines and containers suffer from the same fundamental limitation: startup times of 12+ se…  ( 5 min )

We're entering a new era — one where AI isn't just a tool, but a rapidly evolving force. From GPT-4 to open-source giants like LLaMA and Claude, we're watching machines reason, learn, and sometimes surprise us. But what happens when AI begins to surpass human intelligence in reasoning, coding, and decision-making? Are we prepared for superintelligent systems that can: Build better AIs themselves Hack before humans can patch Influence behavior and decisions subtly The line between science fiction and reality is thinning. 🔍 Developers, what’s your take? Are we building the next leap for humanity — or the next existential threat?  ( 3 min )

Initially, I overlooked Terraform for the past few years, something I never imagined I'll be using. Until for the past few months and now, after falling in love with it, I am proud to announce that I've passed the HashiCorp Certified: Terraform Associate (003) examination and am now officially certified. As someone new to Terraform (just started this year), I aimed to get this certificate not because I want to, but because of necessity: I won't be able to utilize it anymore due to difference in tools used in my current team, so I had to take an initiative by using what I've learned to the fullest and make it worth as much as I can. So for me, I truly believe the Terraform Associate exam is worth it. I had a hard time learning Terraform's opinionated structure -- being much more opinionat…  ( 4 min )

Hey community! 👋 how to optimize like a pro with Memoization, Suspense, and more. 🚀 ✅ 1. React.memo – Stop Unnecessary Re-Renders By default, React re-renders a component when its parent updates—even if props didn’t change. const Button = React.memo(({ label }) => { console.log('Rendered!'); return {label}; }); ✔ Only re-renders when label changes. ✅ 2. useCallback – Stable Functions Across Renders Passing inline functions as props? It causes re-renders. const handleClick = useCallback(() => { console.log('Clicked!'); }, []); ✔ Great for event handlers in child components. ✅ 3. useMemo – Cache Expensive Computations If you compute heavy values on every render, use useMemo to cache the result. const sortedData = useMemo(() => { return data.sort((a, b) => a.value - b.value); }, [data]); ✔ Only recalculates when data changes. ✅ 4. Suspense – Smarter Loading States Instead of conditional rendering everywhere, use React Suspense with React.lazy. const Profile = React.lazy(() => import('./Profile')); ✔ Handles lazy-loaded components gracefully. ✅ 5. Code Splitting – Load Only What You Need Big bundle? Split it into chunks using dynamic imports or tools like Webpack. const Settings = React.lazy(() => import('./Settings')); ✔ Reduces initial load time. ✅ Bonus: Profiler & DevTools Use React Profiler to identify slow components. ✅ Chrome DevTools → Components tab → Profiler 💬 What’s your go-to React optimization trick?

If you've been reading about Cross-Origin Resource Sharing, or CORS in short, there is a good chance that you've come across this term: Preflight Request. It's an extra HTTP request that the browser makes before the actual, cross-origin request to make sure it's safe to send. It's basically an HTTP OPTIONS request that is automatically sent by browsers before certain cross-origin requests. It checks with the web server, and only if the server responds with the right CORS permissions does the browser proceed with the real request, otherwise the browser blocks it. This makes CORS secure: a browser checks both origin and intent before sending your actual data. Let’s break it down with a real example: OPTIONS /resource HTTP/1.1 Host: api.example.com Origin: https://app.example.com Access-Contr…  ( 5 min )

Streamlining Image Integration with Flutter Getting your images into a Flutter app doesn't have to be a chore. With a bit of planning, you can set up a smooth process that saves you time and prevents headaches later on. It all starts with how you organize and declare your image assets. Think about where your images are coming from – are they local files bundled with your app, or are they hosted online and fetched over the network? This choice really shapes how you'll handle them in your code. Having a clear process for getting images into your Flutter project will save you headaches down the road. It's like setting up your workspace before you start building something; everything has its place, and you know where to find it. Here’s a basic workflow to get you started: Organize your images:…  ( 5 min )

I spend most of my day in Slack. Team updates, meeting notes, quick decisions, and follow-ups. It all lives there. Threads move fast, and channels fill up even faster. When I want to use that context with an AI, I end up copying pieces into a prompt, refining them, and explaining what the thread was about. I have done that more times than I can count. It always feels clunky. Slack MCP changes that. It connects directly to your workspace and lets tools work with real conversations in real time using the actual content from your channels and threads. Once connected, you can use the Slack data you already have and respond with the context that matters. In this post, I will show you how to set up Slack MCP and use it to make Claude more helpful with your day-to-day conversations. Think of MCP …  ( 7 min )

Excited to share my latest open-source project: the AI Agent Tester! As AI models become more integrated into our applications, how do we ensure their responses are consistent and reliable? Manually testing prompts is slow and doesn't scale. That's why I created this tool. The AI Agent Tester automates the validation process. It reads prompts from a simple CSV file, sends them to an AI (like OpenAI's GPT), and checks the responses for expected keywords. Here’s what makes it effective: Intelligent Validation: It uses "stemming" with NLTK to recognize word variations (e.g., 'fly', 'flying', 'flew'), making validation more robust. Detailed Reports: It generates a JSON report with the status (Success/Fail) for each prompt, along with the AI's full response. Easy to Use: Built with Python and requires minimal setup. It even has automatic proxy support for corporate environments. This project is for any developer or QA engineer working with Large Language Models who wants to add a layer of automated testing to their workflow. It's open-source, and I would love to get your feedback or contributions! Check out the project on GitHub: https://github.com/lfrichter/ai-agent-test  ( 3 min )

How AI is Reshaping Music As We Know It Did you know that an AI-generated song entered the Billboard charts? Yup, not a typo. A line of code is out there, competing with the likes of Drake and Dua Lipa. Wild, right? I remember when I first heard a track created by AI. I thought, “Wait, so a robot did that?” It had mood, chord progressions, even a hook I hummed all day. And as someone deeply obsessed with melody and meaning, that was both thrilling and a little unsettling. I mean, what does this mean for us musicians and music lovers? Let’s be real: AI music production is no longer just a buzzword—it’s a full-on industry disruptor. But here’s the good news: it’s not about replacing creativity. It’s about supercharging it.

I've been working on a small utility that I've recently published to npm, and my goal with it was to target both a Node.js and a browser environment. In order to accomplish this, I picked up a tool that I've been loathe to touch since the last time I used it, roughly a decade ago — Babel. While I wouldn't actually say there's something wrong with Babel, it does (necessarily) involve lots of complexity. It can be an absolute nightmare to configure, depending on your build process(es). For this relatively simple project, within the space of a week and a half, I wrote, then threw away and rewrote my babel build configuration several times until I was satisfied with the end result. When used correctly, a build process that involves transpilation can strike the sweet spot where you're able to u…  ( 4 min )

Author: Steve Tuohy - Director of Product Marketing Discover how Criteo scaled to 290M queries-per-second, swapped Couchbase + Memcached for Aerospike, cut servers by 78%, and kept sub-ms latency. Criteo serves more than 700 million users daily with personalized ads, processing billions of events in milliseconds. At its peak, Criteo’s infrastructure handles 290 million key-value queries per second (QPS). Until recently, this real-time engine ran on a complex stack of Couchbase and Memcached, propped up by custom C clients and costly operational overhead.

GitHub Homepage: https://github.com/eastspire/hyperlane My fascination with concurrent programming began during a distributed systems course where our professor challenged us to handle 100,000 simultaneous connections on a single server. Most students immediately thought about thread pools and complex synchronization mechanisms. I discovered a fundamentally different approach that revolutionized my understanding of high-concurrency web development. The breakthrough moment came while analyzing the performance characteristics of various concurrency models. Traditional threading approaches quickly hit scalability walls due to context switching overhead and memory consumption. Each thread typically consumes 2-8MB of stack space, making 100,000 concurrent connections require 200-800GB of memory…  ( 6 min )

You’ve Got a Script, But Hate Editing? Yeah, Same So you’ve written a clean YouTube script. Cool. Now what? Start recording? Use Final Cut? Waste an hour googling “text to video free no watermark”? Nah. You typed: “ai youtube script to video in one click” — and I did too. I was desperate for a tool that just lets me paste my script, hit generate, and spit out a watchable YouTube video — voiceover, visuals, everything — with zero headache. And fam, let me tell you — most tools LIE. They say “1-click,” and it turns into 19 clicks + 4 upsells + a watermark slapped on your forehead. So I tested them all. You don’t have to. This post breaks down what actually works if you're trying to: ✅ Turn your script into a legit video ✅ Skip editing completely ✅ Create content for YouTube, not just…  ( 10 min )

In the previous post, we established that simplicity is about reasoning—the ability to clearly understand what a system does, how it works, and why it behaves in a particular way. To understand what impedes that reasoning, this post takes a step back to analyze the fundamental nature of the systems we build. We will borrow insights from the field of cybernetics to dissect how modern software works, on a search to diagnose what precisely makes it complex. In computer science, a "Turing complete" system is capable of performing any computation a theoretical Turing machine can. All modern programming languages are Turing complete, providing the fundamental power to build incredibly diverse applications. However, while the underlying computational engine (the programming language itself, or th…  ( 7 min )

GitHub Homepage: https://github.com/eastspire/hyperlane As a computer science student working on cross-platform projects, I've always been frustrated by the compromises required when targeting multiple operating systems. My experience developing web services that needed to run seamlessly across Windows, Linux, and macOS led me to discover an approach that eliminates platform-specific code while maintaining native performance on all systems. The challenge became apparent during a group project where our team needed to deploy the same web service across heterogeneous infrastructure. Our initial Node.js implementation worked but suffered from platform-specific performance variations and deployment complexities. This experience motivated me to explore alternatives that could deliver consistent…  ( 6 min )

Working with LLMs sometimes means needing to pass custom files whether it's a dataset, a PDF, or logs—to your model. Anthropic makes this easy with their file upload API, and here's how you can do it in just a few lines of Node.js! import fs from 'fs'; import Anthropic from '@anthropic-ai/sdk'; // Initialize the Anthropic client const client = new Anthropic(); async function main() { // Upload a file to Anthropic const file = await client.beta.files.upload({ file: fs.createReadStream('document.pdf'), }); console.log('📁 File uploaded with ID:', file.id); } main().catch(console.error); 🔍 What's happening here? client.beta.files.upload() sends it to Anthropic's servers. Once uploaded, the returned file.id can be used to reference this file in other API calls. ✅ Use Cases Enable retrieval-augmented generation (RAG) workflows. Build smarter assistants with contextual file awareness.  ( 3 min )

GitHub Homepage During my junior year studies, I have been pondering a question: how can we optimize server architecture to the extreme while maintaining functional completeness? Traditional heavyweight frameworks, while feature-rich, often come with issues like high resource consumption and slow startup times. Recently, I encountered an impressive lightweight server architecture that completely changed my understanding of web server design. In my previous project experience, I have used mainstream frameworks like Spring Boot and Django. While these frameworks are powerful, their resource consumption left a deep impression on me. A simple Spring Boot application requires over 200MB of memory to start and often takes more than 10 seconds to boot up. // Traditional Spring Boot application st…  ( 8 min )

In part 1 and part 2 of our Serverless FastAPI series, we covered the development and testing aspects of our FastAPI app. Now we’ll shift our attention to security. Security shouldn’t be an afterthought, however, the theme of this series has been to get you up and running in a manner that is beginner-friendly, whilst also exposing you to shortcomings and approaches in an organic way. Up until now, our Lambda Function URL has been publicly accessible, allowing every opportunist, every bad actor and their collective to have an open pass with an unprotected API provided they can find the endpoint URL.

In software architecture, Push and Pull models define how data flows between a producer (like a server) and a consumer (like a client). While both are valid, choosing the right one can significantly impact user experience, system performance, and scalability. In a Push model, the server initiates the communication. It sends (or "pushes") data to the client whenever something new happens. The client doesn’t have to ask—it just gets notified. Low latency Real-time experience Efficient for frequent updates More complex to implement Harder to scale with many clients 🧠 Examples: WebSockets, Firebase Realtime Database, Server-Sent Events In a Pull model, the client initiates the communication. It regularly or occasionally requests data from the server, asking, “Do you have anything new?” Simple…  ( 4 min )

If you’ve just installed Python on Windows and when trying to run python from the Command Prompt you see this message: "Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Apps > Advanced app settings > App execution aliases." Don’t worry This is a common problem caused by Windows redirecting your Python commands to the Microsoft Store. In this post, I’ll walk you through the exact steps to fix it, so you can start coding right away. What Causes This Issue? Windows 10 and 11 have a feature called App Execution Aliases that adds shortcuts for certain apps, including Python. If Python isn’t properly installed or the PATH isn’t set, Windows tries to redirect your command to the Store to download Python. This causes confusion because even if you installed Python manually, typing python will still bring up this message. Step-by-Step Fix: Disable Python App Execution Aliases Step 1: Open Windows Settings Press Win + I on your keyboard This opens the Settings window Step 2: Navigate to App Execution Aliases In Settings, click on Apps Then click on Advanced app settings (or search for “App execution aliases” in the Settings search bar) Scroll through the list until you find: python.exe python3.exe Step 3: Disable the Aliases Step 4: Verify the Fix Bonus Tips If you don’t see Python in your PATH, you can manually add it by editing your environment variables. Use python -m pip instead of just pip to ensure you’re using the correct pip for your Python version. Summary Disabling the Windows App Execution Aliases for Python is a quick and effective fix for the “Python was not found” error. Once disabled, Windows stops redirecting your commands to the Microsoft Store, and you can run Python smoothly from the terminal.  ( 4 min )

Your University Website Will Never Go Down Again — Beginner Friendly System Design Let’s create a very simple and absolute beginner-friendly system design for our university website. On usual days when no results are declared, no announcements are made, and no admit cards are released, the traffic on the website is very normal. In an ideal case, let's start from a very simple design — no load balancer, no auto-scaling, none of those typical complex components. Server: This can be any highly configured machine that is up and running 24/7. Technically, your personal laptop can also act as a server — but obviously, no one wants that. DNS (Domain Name System): It’s a global directory that maps domain names to IP addresses. You pay for that public IP. At the time of result declaration or admit card release, traffic increases drastically. The same server configuration cannot handle the sudden surge in requests. The result? The application faces downtime or crashes. So, what can we do? We can increase the configuration of the server from: 4 CPUs → 8 CPUs 64 GB RAM → 128 GB RAM This is called Vertical Scaling, which means increasing the power of the existing machine. We cannot increase the configuration of a running server. First, we need to stop the server, upgrade it, and then start it again — which causes downtime. It’s not recommended for high-availability applications. So, what else can we do? We can use Horizontal Scaling, where we replicate the resources — basically, we add new servers instead of upgrading the existing one. A new IP will be assigned to each new server. But, all requests will still go to the original server unless we have a way to distribute traffic. Any idea how to solve that? Well, this is what I’ll discuss in the next design! 🚀 Stay tuned for the next part where we’ll talk about load balancers, traffic distribution, and more smart strategies to handle peak-time traffic without breaking the system! ✍️ Author: Omkar Sharma 📬 Feel free to connect on LinkedIn or explore more on GitHub  ( 4 min )

This may sound like the worst idea ever. But I think there is no better time than now. Despite new frameworks popping every week, devs' burnout keeps escalating; the ecosystem is bursting at the seams, and Vercel monopoly gives billing nightmares. For my solution to succeed, it just needs to be: Composable components, shared and local state, reactivity. Natural SSR (not by running front-end code on the server), fast loading, functional href, real FormData, and execution transparency (that was lost). Static endpoints only for serving files and pages. Everything else — wrapped and secured by framework. Not required to write/run, but not rejected if integration is needed.

Chat interfaces have surged in popularity, becoming a common entry point to intelligent systems. But while text excels at expressiveness and simplicity, it's often limiting for structured interactions. Booking a meeting, selecting options, or reviewing results all demand more than just words. The immediate solution that comes to mind is to render traditional user interfaces (components) inside the agentic system, but what does that look like in practice? What are the viable strategies for embedding UI into chat-driven workflows? And even better: should you be embedding UI at all? If so, will these new approaches eventually replace traditional interfaces, or simply augment them? In this article, we are going to look at the three emerging strategies for returning UI from agents: First-party …  ( 8 min )

Artificial intelligence (AI) is not a far-fetched concept - it is a network of intelligent agents that have been built into our daily routines and business procedures. These agents perceive, reason, and act to resolve issues on our behalf. Some work in the background, making quick safety decisions on factory floors. Others adjust throughout time, predicting our demands at home and at work. Understanding how these agencies work and the measures they take may inspire ideas for how your own sector can benefit.

Building a Custom Video Editing Backend with LLMs and Declarative Composition I’ve been exploring how large language models (LLMs) can be used to automate video editing. At first, I thought the process would be relatively straightforward: describe the edit in natural language, have the LLM translate that into actions, and render the result. Initially, I tried using FFmpeg with LLMs to handle basic video operations like trimming and transitions. But it didn’t work well. The generated code was brittle, and FFmpeg’s syntax is not easy for LLMs to handle reliably, even with refined prompts. To solve this, I created a custom markup system called Swimlane Markup Language (SWML) — a JSON-style declarative format that describes the video structure. It allows LLMs to express compositions in a for…  ( 4 min )

The world of generative AI is expanding at an incredible pace. Developers now have access to a powerful array of Large Language Models (LLMs) from providers like OpenAI, Google (Gemini), Anthropic (Claude), and a vast collection available through services like AWS Bedrock and Hugging Face. While this choice is empowering, it introduces a significant challenge for engineering teams: each model comes with its own unique API, SDK, and authentication mechanism.

Introduction 📘 So many developers won't have even touched assembly language let alone decide to write a whole program in it. This is understandable, reasons to write assembly are few and far between. However the knowledge you gain from doing as such can help build a deeper understanding of how computers function helping you write better more efficient code even in other programming languages. So to start off lets take a look at what "x86 Assembly" actually means. Assembly code is device specific meaning code that runs one one machine might not work on another. This is because CPUs can have different architecture and therefore expect different instructions. Each architecture will have a certain set of instructions that the CPU is designed to use. Here we are using the x86 architecture w…  ( 12 min )

I used AI to help me create some diagrams and it was so convenient that I wanted to share the process.

Inheritance It is a way to pass the properties and functionality of the parent to the child is called as inheritance. It helps us achieve code re-usability. NOTE:- Without a constructor, we can not achieve inheritance because with the help of the parent instance, we can access the parent properties and functionalities. Types of inheritance- Single Multi-level Hierarchical Hybrid Multiple(We can achieve with Interface in C#) In this inheritance, one parent class has only one child class. In this inheritance, the chaining of the parent and child classes occurs. In this inheritance, one parent class has two or more child classes. This is a combination of two or more types of inheritance. C# does not support multiple inheritance of classes (a class cannot directly inherit from two or more classes). However, it achieves a form of multiple inheritance through interfaces NOTE:- We will discuss the Interface in another post. Link:- Coming soon... or check my profile.  ( 3 min )

This is a submission for the World's Largest Hackathon Writing Challenge: After the Hack. What began as a hackathon sprint evolved into a long-term journey toward intelligent living. HomeWhisper, our AI-powered smart home dashboard, was built to unify fragmented IoT experiences — and in doing so, it unified our team’s vision around creating technology that feels personal, adaptive, and almost invisible. But the story didn’t end when the hackathon timer stopped. In many ways, it was just beginning. Hackathons stretch you — but after the hack is when the real transformation happens. I (@aniruddhaadak) dove deeper into UX for AI interfaces, learning how to guide users across multimodal experiences (voice + gesture). We weren’t just building features. We were becoming better designers, collabo…  ( 5 min )

An Application Programming Interface (API) is a critical component in modern software development, acting as a bridge that allows different systems or components to communicate seamlessly. APIs define how requests and responses should be structured, enabling developers to interact with a system without needing to understand its internal workings. In this article, we'll explore what an API is, key principles for designing effective APIs, and best practices to ensure they are robust, scalable, and user-friendly. We'll also include flowcharts to illustrate the API design process and interaction flow. What is an API? 1. Parameters: The inputs the API expects (e.g., query parameters, headers, or body data). 2. Responses: The data the API returns, typically in formats like JSON or XML. 3. Errors…  ( 6 min )

In an age where web browsers are practically mini operating systems, complete with GPU acceleration, sandboxed processes, and memory footprints that rival AAA games, there's something refreshing about using a browser that simply displays content. Enter Lynx, a text-based browser that's been quietly doing its job since 1992. No tabs, no ads, no JavaScript... no nonsense. It feels genuinely nostalgic to use. Plus, there's a certain charm in telling people you browse the web from the terminal. Lynx is a terminal-based web browser that runs in plaintext environments. It supports browsing over HTTP, HTTPS, FTP, and, yes, even Gopher. Designed originally at the University of Kansas, Lynx predates many of the web's now-essential features. For example: It doesn't support JavaScript. It doesn't r…  ( 7 min )

Originally posted on https://medium.com/c-sharp-programming/all-the-net-core-opsy-things-37b2e21eabb4 This guide began as a conversation between me and someone exploring how to containerize .NET apps. The same questions kept coming up; from new developers to infrastructure and DevOps engineers and I kept pointing people to the docs. I decided to turn it into a practical walk through and post it here for anyone who finds it useful. When you pull an image from mcr.microsoft.com/dotnet/*, you're getting more than a runtime; you're pulling from a carefully layered set of container images, each designed to be lightweight, secure, and purpose-built. Understanding these layers makes it easier to troubleshoot, secure, optimize performance, and pick the right image for your use case. Imag…  ( 6 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My deep dive into context management began during a performance optimization project where I discovered that inefficient request context handling was creating memory leaks and performance bottlenecks. Traditional web frameworks often treat context as an afterthought, leading to resource waste and complex state management. This experience led me to explore how sophisticated context management can dramatically improve both performance and developer experience. The pivotal insight came when I realized that request context isn't just about passing data between functions—it's about creating an efficient, type-safe mechanism for managing the entire request lifecycle. My research revealed a framework that implements context management patter…  ( 9 min )

RAG Chatbot - MoviesGPT Harith Y ・ Jul 24 #rag #ai #chatbot #llm  ( 2 min )

What is RAG? Retrieval-Augmented Generation or RAG is when you change the output of a Large Language Model (LLM) by providing the model more context alongside a user’s input. That way, the model can use its ability to generate text along with extra context to provide accurate answers to users’ questions Cost Effective Models have cut-off dates, after which knowledge isn’t updated. Covers up for information that does not exist A popular technique to represent information in a format that algorithms, especially deep learning models, can easily process. This ‘information’ can be text, pictures, video or audio.

Supercharge Your Recruiters: Building AI-Powered Automation in Salesforce with Agentforce Hemant Jawale ・ Jul 22 #ai #saas #agentforce #salesforce  ( 2 min )

GitHub Homepage During my junior year studies, I have encountered many different web frameworks, from Spring Boot's "convention over configuration" to Django's "batteries included." Each framework has its unique design philosophy. Recently, I discovered an impressive web framework that adopts a completely different design philosophy—zero-dependency design. This minimalist design philosophy made me reconsider the essence of software architecture. In my previous project experience, dependency management has always been a headache.

MCP Inspector provides a clear UI to view and interact with the server's available tools, prompts, and resources. Unlike generic API testing platforms, it is tailored to the Model Context Protocol (MCP), offering native support for inspecting each part of the protocol. This article outlines the key interface features and explains how they work internally. The Inspector communicates with our MCP server over a WebSocket proxy, which wraps the low-level transport (like stdio or streamable-http) into a live browser-based session. As we interact with the UI, it sends JSON-RPC messages to the server based on our actions and displays the responses in real time. Tools tab uses schema from the server manifest to generate parameter input fields. When a tool is run, Inspector constructs a tool-use JS…  ( 5 min )

A step-by-step journey into building a flexible, multi-provider RAG application that lets you talk to your documents. We’ve all been there: staring at a 100-page PDF, knowing the answer to our question is buried somewhere inside. Skimming through dense academic papers, legal documents, or technical manuals is a tedious process. What if you could just… ask the document a question and get a straight answer instead of doing Ctrl+F multiple times? That’s exactly what I set out to build: an interactive chatbot that ingests any PDF (not 1 but many hehe) and allows you to have a natural conversation with it.

I started watching the show Severance (no spoilers, please!) and the office arrangement caught my attention. So I decided to replicate the desks using HTML and 3D CSS. It may not be the best office culture example, but it's an office and it's pop culture... so it counts as office culture? 😅 Journey I started by defining a generic "cube" figure with two components.

Puedes leer todo el articulo en mi sitio web byandrev.dev. Uno de los elementos fundamentales en el diseño de interfaces web es el aspect ratio o relación de aspecto. En pocas palabras, el aspect ratio se refiere a la proporción entre la altura y el ancho de un elemento, este elemento pueden ser imágenes o videos. Algunos de los aspect ratio más conocidos son los siguientes: Para definir el aspect ratio de un elemento debes hacer lo siguiente: selector { aspect-ratio: ancho / alto; } .image { width: 100%; aspect-ratio: 16 / 9; } Con el aspect ratio evitamos el layout shift, este es algo muy incómodo que suele suceder en los sitios webs. El layout shift hace referencia al movimiento inesperado del contenido de la web cuando los elementos están cargando.

我是个写代码有洁癖的人 作为一名长期从事软件工程与架构设计的开发者，我主要涉猎： 后端语言：Golang、Java（Spring Boot）、C++、Python 前端 / 客户端开发：Next.js、Vue、Flutter、Android 原生（Java/Kotlin）、iOS SwiftUI 在过去数年的项目开发中，我习惯于从系统架构层面出发，先理清数据流、业务边界、模块划分，再开始编码。 代码不是写出来“能跑”就够了，而是要“经得起阅读、维护、迭代”。 代码要干净，架构要合理，安全性、稳定性与性能缺一不可。 但遗憾的是，在我与多家马来西亚本地软件公司合作的过程中，这些最基本的工程理念，经常被无情践踏，甚至被当作“累赘”对待。 在马来西亚，很多中小型软件公司普遍存在一种奇怪的开发心态： “只要客户不投诉，交付能上线，代码再乱也没关系。” 他们认为编码风格、架构规范、安全防护，都是“锦上添花”的“奢侈品”，而不是“必须品”。 但从一个架构师的角度出发，我看到的却是： 系统极度耦合、不可维护 安全漏洞触目惊心 UI/UX 设计极其草率 代码层面充满重复、拼凑、无测试的“代码垃圾” for 循环暴力构建 UI 这家公司在开发 Flutter 项目时，明明是异步数据渲染的场景，居然用 for() 循环硬刷 widget 列表，而不是 StreamBuilder 或 FutureBuilder。 结果造成页面卡顿、状态错乱、异常频发。 “这样比较快写完，而且能跑啊。” 这是快速交付吗？不，这是对框架机制的践踏。 这家公司到现在还在靠“打印源码纸质档案”做版本控制。每个月月底，把项目代码全部打印下来，装进文件夹归档。 没有 Git，没有 commit log，没有代码 diff、pull request，全靠纸质比对。 我问：“那多人协作开发怎么办？” 🤦‍♀️ 我无语到失语，21 世纪了，软件开发靠打印来备份？这是开发还是玩穿越剧？ main.dart 塞 9000 行代码，自称 MVC 这个项目让我窒息： 所有页面和逻辑集中写在一个文件：main.dart 文件长达 9000 多行，包含十几个 class 和若干 void main() 函数 所有 UI 控件都用 Container 伪装 AppBar、FAB、BottomNavBar 每个组件都嵌套一个新的 MaterialApp 开发者说他们有在使用“MVC 架构”， main.dart 里。 你这不是 MVC，这是MCU（Marvel Cinematic Universe）宇宙坍缩。 一个 React Native 项目，管理员账号密码直接硬编码在代码里： const adminUsername = "admin"; const adminPassword = "123456"; 然后这家公司还拒绝引入 .env 或加密方案，理由是： “麻烦，没时间搞。” 你上线的是一个拥有后台权限的应用诶，不是你家门口的电灯开关。 这种行为说难听点就是：主动裸奔，还怪天气太热。 这家 Java 后端项目更是让我大开眼界： 所有接口都用 GET 请求（包括用户创建、修改、删除） 没有使用 ORM，全靠拼接 SQL 没有使用 OOP，全程 procedural 密码字段以明文存储在 MySQL 中，无加密、无 Hash、无 Salt 他们甚至说这“更方便调试和查询”。 但你知道这代表什么吗？ GDPR、PDPA、安全合规这一类根本不在他们的词典里。 在我指出问题后，常常收到的回应是： “我们以前写 Delphi 的” “我是从 C# 转过来的” “语言不同，写法也不同” “客户看不到代码，能跑就行” 我只想说： 我也写过 COBOL 给银行做核心系统，也写过用 Erlang 实现的电信 SIP 调度项目。 我曾向某马来西亚交通部相关 Flutter 项目的团队报告严重的用户信息泄露漏洞（泄露包括身份证号码、用户实名、注册地址等全套数据）， 我还完整撰写了报告并发布于我个人漏洞档案页： 🔗 Bug Bounty 案例分析 - 2025年3月24日 直到今天，无回应，无修复，无公告。 这样的官方项目都如此对待数据隐私，让我深感寒心。 我不是在否定整个马来西亚软件行业，的确也有认真负责的团队，但在我所接触的百余家公司里： 至少 70% 存在严重的技术不规范与安全意识缺失的问题。 我写这篇文章，不是为了抱怨，而是为了敲响一个警钟： 写烂代码可以短期交付，但你留不住客户 系统架构乱七八糟，维护的人每天都在流血 UI/UX 随意堆砌，用户体验烂掉，产品不会有未来 你写代码的方式，就是你做人做事的方式。 你代码乱，我也会怀疑你的生活方式是不是也一团糟。 你是否也经历过这些“地狱级”的开发现场？ 欢迎留言，我们一起来聊聊 —— 别让“能上线”成为你对技术的全部理解。  ( 3 min )

Inheritance in Java Sundar Joseph ・ Jul 24 #webdev #java #beginners #devops  ( 2 min )

Java Inheritance is a fundamental concept in OOP(Object-Oriented Programming). It is the mechanism in Java by which one class is allowed to inherit the features(fields and methods) of another class. In Java, Inheritance means creating new classes based on existing ones. A class that inherits from another class can reuse the methods and fields of that class. In addition, you can add new fields and methods to your current class as well. Why Use Inheritance in Java?Code Reusability: The code written in the Superclass is common to all subclasses. Child classes can directly use the parent class code. Key Terminologies Used in Java Inheritance: Class: Class is a set of objects that share common characteristics/ behavior and common properties/ attributes. Class is not a real-world entity.

If you're developing a Web3 product, your first step might be to look for a backend developer. But in many cases, what your project truly needs is a developer who can bridge traditional backend systems with decentralized infrastructure. You need someone who understands how to write smart contracts, connect wallets, structure token logic, handle gas fees, manage on-chain/off-chain bridges, and still build APIs that don’t fall apart when MetaMask pops up. In short: you need a Web3 integrator. 🧠 What’s a Web3 Integrator? Their job isn’t just to build. It’s to bridge: Between your dApp frontend and the blockchain. Between smart contracts and databases. Between real users and token logic. Between hype and real functionality. They understand gas optimization, contract upgrades, wallet UX, and how to prevent front-running. And they also know how to make sure your app still works if a Web3 provider goes down. 🧱 Why Backend Devs Alone Won’t Cut It Smart contracts are written as an afterthought (and need a rewrite). Blockchain calls aren’t gas-efficient. Users get stuck on wallet errors. Events aren’t emitted, so debugging becomes hell. They build everything off-chain “for now” - which becomes “forever.” The result? A product that looks decentralized... but isn’t. Or worse, it doesn’t work at all when real users show up. 🚧 Real-World Tasks a Web3 Integrator Owns Setting up contract factories and linking them to frontend flows Building REST or GraphQL APIs that read from the blockchain Indexing smart contract events with The Graph or custom logic Creating secure auth flows with wallet sign-ins Managing token gating, vesting, and permissions Ensuring replay protection and preventing MEV vulnerabilities Building fallback systems when chain RPCs go down Auditing and testing everything before mainnet deploy This isn’t stuff you can slap together in a weekend sprint. Final Thought You need someone who gets the full stack - including the parts that live on-chain.  ( 4 min )

Modern .NET developers often lean on async/await to build performant APIs and services. But here's a critical truth: Using async/await in a synchronous communication model doesn’t make your system asynchronous. This misunderstanding is common in RESTful and gRPC-based architectures. It often leads to bottlenecks, false scalability assumptions, and overly tight coupling between services. Let’s dive into the core of the issue what asynchronicity really means, how it's different from non-blocking code, and why REST/gRPC are inherently synchronous, even when wrapped in async/await. 🔗 Synchronous Systems Example: var user = await _userServiceClient.GetUserAsync(userId); Even though you're using await, the service cannot continue until it receives a response from the _userServiceClient.

It features a hero section, team spotlight, upcoming events carousel, quick links, and a sticky sidebar with live widgets (clock, weather, notifications). I aimed to create a dynamic, user-friendly space with personalization (drag-and-drop widgets), dark mode, and smooth animations for an interactive experience. Demo Link Repo Link I started by planning a clean layout that mimics a real company intranet, then built the structure in HTML and styled it for a modern, responsive design with CSS Grid and Flexbox. After that, I added interactivity with JavaScript, including dark mode, an auto-sliding event carousel with swipe support, and a sticky sidebar with real-time widgets (clock, weather, and notifications). One of my proudest choices was implementing drag-and-drop widgets in the sidebar with Local Storage, giving users the ability to personalize their dashboard.

In this post, I'll share the process I used in building BreezeQ2 — a Node.js background job tool with a focus on scalability and high performance. Before we go further, here's a brief video showing how the system works: It took me between 12 to 20 hours, spread over five days. Is it still considered vibe coding if it took that long? Through building BreezeQ, I discovered a reliable approach that balances AI assistance with enginee…  ( 6 min )

In the current technology landscape, "AI-powered" is often treated as a definitive badge of innovation. Investors are drawn to it. Customers expect it. And businesses everywhere are scrambling to ride the hype. However, the strategic application of AI is a matter of precision, not trends. Adding AI "just because" can drain budget, burn out teams, and dilute everyone’s focus on the real goals. The critical question is not if you can use AI, but why you should. Below is a step-by-step guide that’s designed to help you decide with clarity. AI excels in tasks that require cognitive-level processing. To determine if it’s the right fit, diagnose your own situation with a foundational question: Is there an intellectual process I’m trying to automate? If your answer is no, and the task can be so…  ( 6 min )

When building web applications with Next.js, one of the most critical — and often overlooked — decisions is how to structure your project. Should you start with a simple monolithic setup? Should you organize your features modularly? Or are you aiming for a fully scalable microservices or serverless architecture?

Whether you're building a small side project or architecting a production-grade platform, this article will help you choose and implement the right structure for your needs. Let's dive into the architecture landscape of Next.js and learn how to build applications that are scalable, mai…  ( 11 min )

I have been (and still am) a big fan of Obsidian, Notion, Emacs Org-Mode and other multi-purpose productivity apps. They are so flexible that you can do almost anything with them! ... I have also found that their flexibility is their biggest downside. If you have ever used Obsidian or Emacs Org-mode, chances are that you ended up trying to use it for everything - note taking, day planning, gym routine tracking, personal finance and the list goes on. I have found that Obsidian and Org-mode are really good for note taking. And that's it. That's where it should stop. Everything I’ve tried to make it work for other purposes has always felt like a hack. "Oh sure, I don't mind using a text editor with my thumbs on my phone to fill out my reps in the gym, it's not hard at all". "I don't mind t…  ( 5 min )

After I read the blogpost it was the first time I was thinking of checking out the editor. The catchphrase of Zed is, the world’s fastest AI code editor. So why are they allowing us to disable all AI features? their point of view is very pragmatic. Most AI tools prefer to divide people in AI optimists and AI pessimists. And all other situations are swept under the rug. Sadly Zed is in the shadow of Cursor and Windsurf. As far as I know you can turn off some AI features, but not all, in those apps. The following question is, are going developers going to pick Zed over Cursor or Windsurf because of the versatile AI choices? I'm using the Jetbrains editors, and I rely on the auto complete to make the typing faster. I'm using AI to write bigger pieces of code, so basically as a typist with some technical knowledge. And for things I'm not sure of. AI providers make not logging in a very annoying experience. So I think it will not be long before I will explore running local AI's. I invite the AI optimists who think we won't even need editors in the future because AI is just going to write machine code from the specs and code history. Think about your current way of working, and how would you improve it? Let us know it in the comments.  ( 4 min )

When it comes to hosting Node.js applications, you’re faced with a choice: build and manage your own infrastructure or use an orchestrator like Stormkit, purpose-built to scale and simplify, especially for managing multiple apps or hundreds of long-lived processes.

The vision of blockchain interoperability—seamless communication between sovereign networks—has transitioned from theory to implementation. Today, Cosmos, Polkadot, and Avalanche represent the leading contenders in what is being called the "layer-zero" race: the battle to become the foundational communication layer for Web3, similar to what TCP/IP is for the traditional internet. Each project brings a distinct architectural approach and set of trade-offs that impact where developers build, how assets move, and what standards may ultimately dominate. Cosmos launched its Inter-Blockchain Communication (IBC) protocol in 2021 and has since built the largest production-grade interoperability network in the ecosystem. Over 115 independent blockchains are connected via IBC, moving over €900 milli…  ( 5 min )

GitHub Homepage During my junior year studies, server-side push technology has always been a key focus area. Compared to traditional client polling, server-side push enables true real-time data transmission, significantly improving user experience. Recently, I deeply studied a Rust-based web framework whose Server-Sent Events (SSE) support gave me a completely new understanding of modern push technologies. In my previous projects, I tried various traditional push technology solutions. While traditional Ajax polling is simple, it's inefficient and wasteful of resources. // Traditional Ajax polling implementation class TraditionalPolling { constructor(url, interval = 5000) { this.url = url; this.interval = interval; this.isRunning = false; this.timeoutId = null; } star…  ( 8 min )

NoSQL databases have become a cornerstone of modern application development, offering a flexible and scalable alternative to traditional relational databases. Unlike relational databases that rely on structured tables and SQL, NoSQL databases store data in formats like key-value pairs, documents, or graphs. In this article, we'll explore what NoSQL databases are, their advantages and disadvantages, when to use them, and why some applications avoid them. We'll also include a flowchart to illustrate how NoSQL databases fit into application architectures. What Are NoSQL Databases? For example, a key-value NoSQL database might store user data as: Key: user123 Value: { "name": "Alice", "email": "alice@example.com" } This simplicity makes NoSQL databases like Cassandra, MongoDB, or Redis popul…  ( 6 min )

Building a Cross-Browser Screenshot Extension: My Journey with Kiro The Challenge I'm a student who loves using online lectures but hates messy screenshots—especially when YouTube's video controls show up, or when I have to painstakingly sort images into folders afterward. That's why I built YouTube Screenshot Helper for Chrome: it let me capture the perfect lecture slides and kept my schoolwork organized without the hassle. But then reality struck: not everyone uses Chrome. When I tried to bring the same magic to Microsoft Edge, I quickly learned that browser compatibility isn't just about copy-pasting code. Edge threw its own set of problems at me—from stubborn storage quirks to security restrictions that seemed designed to make any kind of folder structure impossible. Here'…  ( 5 min )

There's a good chance you are not getting the best out of your LLM (Large Language Model) not because the model isn't powerful enough, but because your prompt isn't. Maybe you are too quick to ask a question before structuring your thought or it could be that you are not giving your LLM enough context. In my early days of writing prompts, I found myself doing something interestingly odd which is giving my rough prompt to another LLM just to see how it would rewrite or improve it and most times the results are often better, more structured and often closer to what I actually needed. At the time, I didn’t have a name for this process. It just felt like I was refining a prompt through another prompt. But few weeks ago, I learned the actual term which is called meta prompting. That's when it …  ( 9 min )

GitHub Homepage As a junior computer science student, I gradually recognized the importance of asynchronous programming during my web development learning process. Traditional synchronous programming models often cause thread blocking when handling IO-intensive tasks, while asynchronous programming allows programs to continue processing other tasks while waiting for IO operations. Recently, I deeply studied a Rust-based web framework whose asynchronous programming implementation gave me a completely new understanding of this technology. In my previous projects, I used traditional synchronous programming models. While this model has clear logic, it encounters serious performance bottlenecks when handling large numbers of concurrent requests. // Traditional synchronous programming example @R…  ( 8 min )

Here’s a quick breakdown of what a typical Azure DevOps pipeline looks like — straight from commit to production: Run basic checks — linting, build, unit tests. If something fails, no merge. Keeps bad code out early. Once merged, CI kicks in. It runs integration tests, pulls secrets from Azure Key Vault, and builds the container image. Keeps the codebase stable. Deploy to staging (e.g., AKS). Run acceptance tests. Add a manual approval step if needed. Make sure everything works before going live. If staging is green, promote the image to production. No rebuilds. No surprises. Use Azure Monitor + Container Insights for logs, metrics, health checks. Application Insights helps debug real issues fast. Defender for DevOps helps with static code analysis and pipeline-level security. Set it up once — saves you later. That’s it — a reliable, secure pipeline from PR to production.

GitHub Homepage As a junior student, I often need to switch between different operating systems during my web development learning process. The Windows computer in my dorm, the Linux server in the lab, and my personal MacBook each have their unique development environments. This multi-platform development requirement made me deeply appreciate the importance of cross-platform compatibility. Recently, I discovered an impressive web framework whose performance in cross-platform support made me reconsider the possibilities of web service development. In my previous project experience, cross-platform development has always been a headache. While Java's Spring Boot can achieve "write once, run anywhere," the resource consumption and startup time of the JVM are daunting. Although Node.js can run …  ( 8 min )

My Linux Services Monitor (Simulated) – Built with Google AI Studio Prompt: Build a simple web app using vanilla JavaScript, HTML, and CSS called "My Linux Services Monitor." It should display a list of fake Linux services like ssh, cron, and cups. Each service should have a randomly assigned status: "Running," "Stopped," or "Failed." Use a button labeled “Refresh Status” that re-randomizes all the statuses. Use color-coded labels or icons to indicate each status (green = running, gray = stopped, red = failed). Keep the UI clean, readable, and beginner-friendly. No backend, no frameworks, no TypeScript. AI Studio created the html, css and js code. It displays a list of common system services (like sshd, cron, cupsd, etc.) along with their current status: Running, Stopped, or Failed. A refresh button lets you simulate status updates, randomly changing the state of each service. Important: This is a mock simulator, not connected to an actual Linux system. The status of each service is randomized with each refresh to demonstrate layout, interactivity, and dynamic behavior in a web app. The purpose of this project was to test what Google AI Studio could generate from a natural-language prompt — and to explore how it could help someone without a programming background (like myself) spin up functional web UI quickly. A fully working version would require additional development — specifically a backend component to read real system data (via systemctl or similar) and pass it to the frontend securely. Still, as a learning tool and a prototype, this shows how far you can go with AI-assisted code generation using only a prompt. I think this was the goal of the challenge. I'm a retired electronics tech and programming is my avocation — if I can get this far with Gemini AI Studio, anyone can.  ( 3 min )

Originally published at dileeparanawake.com Agile has become a buzzword — but feedback still saves us. Optimism becomes delusion when we STOP absorbing feedback. If we become deluded, we get blind spots and we can miss the things that will sink us. For me personally this is why one of the most important principles of the Agile manifesto is “At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behaviour accordingly.” Second to that it is: “the Art of maximising work NOT done" read more. Feedback, retrospectives, iterating the scope is key. This applies in my technical solo projects, my team projects and in life. You’re not delusional when you’re wrong. You’re delusional when you don’t test if you’re wrong. Build a small, meaningful part — get feedback — adjust. Agile has become such a buzzword and a certified set of mindless rigid processes I feel the intent of agile is often lost in the processes. I think we need to get back to the intent, and less of the performance. What’s your favourite Agile principle? Why?  ( 3 min )

I've decided to do a new blog series where I’ll be sharing coding challenges I’ve solved each week. For our first entry, I’ll walk through the classic Subsets II problem, which involves returning all possible unique subsets in an integer array that may contain duplicates, demonstrating how to approach it, step by step, using one of the most fundamental algorithmic techniques: backtracking. Here’s the problem statement: You are given an array nums of integers, which may contain duplicates. Return all possible subsets. The solution must not contain duplicate subsets. You may return the solution in any order. You can also find a more detailed problem statement here. The goal is to produce every possible subset from the input array, while ensuring that no duplicate subsets are included in th…  ( 5 min )

Converting a design into code used to be a lengthy process with lots of back and forth between design and development teams. The handoff process could create bottlenecks and slow down product creation, as the whole process was very manual and sometimes required trial and error and lots of thinking to see if it was viable and practical to build out a new feature or component. These days, the process is considerably less intensive and even more improved because of the sheer magnitude of vibe coding tools available on the market. Vibe coding has revolutionised the way designers and developers work because now artificial intelligence can understand both your design and code files, making it a pretty straightforward process to generate working applications.

Imagine trying to bake a cake with a team of chefs, but each person works on their ingredient separately for weeks before combining everything at the end. The result? A disaster of conflicting flavors, burnt edges, and a final product that nobody wants to eat. This scenario perfectly describes how software development used to work—and why CI/CD pipelines have become the secret ingredient to modern software success. Not too long ago, software development was dominated by the waterfall model, where each stage of development happened sequentially. Teams would work in isolation for months, only to face "integration hell" when trying to combine their work. The result? Incredibly long release cycles and painful deployments that often failed spectacularly. Today's reality is strikingly different.…  ( 6 min )

GitHub Homepage: https://github.com/eastspire/hyperlane During my advanced systems programming course, I became obsessed with understanding how data moves through web servers. My professor challenged us to minimize memory allocations in HTTP request processing, leading me to discover zero-copy techniques that fundamentally changed my approach to web server optimization. This exploration revealed how eliminating unnecessary data copying can dramatically improve both performance and memory efficiency. The revelation came when I profiled a traditional web server and discovered that a single HTTP request often triggers dozens of memory allocations and data copies. Each copy operation consumes CPU cycles and memory bandwidth, creating bottlenecks that limit server performance. My research led m…  ( 7 min )

We’ve been dealing with supplier product catalogs in different formats (CSV, XLSX, JSON), and the data is usually all over the place. Instead of cleaning it up by hand every time, we put together a small CLI tool. It maps fields, transforms values, remaps categories, and can generate IDs if needed. Configurable via YAML. You run it, and get a clean CSV or JSON output. It’s open-source. No UI, no integrations, just a script that does one job.

As a C# developer, one of the most debated design decisions I've made (and seen others struggle with) is this: "Should I use an interface, an abstract class, or a mix of both?" It's not just about syntax or style, it's about shaping the future of your application. If you're building an extensible API, working on a SaaS platform, or simply trying to write better C# code, this question can dictate how testable, maintainable, and resilient your solution becomes. In this post, I'll walk you through my personal learnings (and scars) from dealing with these choices, with links to in-depth posts for those who want to go deeper. Think of interfaces as promises, they define what a class can do without caring how it does it. For example, an INotificationService contract can be implemented via Email,…  ( 5 min )

Before I was deep into high-horsepower builds, I was in business leadership — scaling operations, solving process problems, and optimizing teams. But it wasn’t until I got my hands greasy in the garage full-time that I realized: building cars and building systems aren’t that different. When I work on a 1,000+ HP Hellcat or prep a car for drag racing, I approach it like I would any complex system: Identify constraints (fuel flow, temperature, traction) Optimize inputs (timing, pressure, airflow) Test and iterate — always Use data, not assumptions Just like code needs debugging, performance machines need diagnostics. Both worlds depend on feedback loops and fine-tuning. In my previous life, I was a Senior VP in the insurance space. We scaled to $620M revenue by making smart process moves.

Two years ago, I was a backend developer stuck in my comfort zone. Here's how learning frontend changed my entire career trajectory. I was working as a Node.js developer at a mid-sized startup in Pune's Hinjewadi area. Good salary, decent work-life balance, but something felt missing. Every time I had an idea for a feature improvement, I had to explain it to the frontend team, wait for their bandwidth, and hope they understood my vision. The frustration was real. In late 2022, I wanted to build a simple expense tracker for my family. I had the backend ready in a weekend - REST APIs, database schema, authentication, everything. But when it came to the frontend... I was stuck. I tried hiring a freelancer for ₹15,000, but the communication gap was huge. The UI looked nothing like what I had i…  ( 5 min )

1. Tư duy phát triển (Growth Mindset) Tin tưởng vào khả năng phát triển: Thay vì nghĩ rằng tài năng là bẩm sinh, hãy hiểu rằng nỗ lực và sự kiên trì có thể giúp bạn tiến bộ. Xây dựng thói quen học tập hàng ngày: Dành ra thời gian cố định mỗi ngày để học sẽ giúp bạn tạo kỷ luật và gia tăng hiệu quả học tập. Tạo môi trường học tập tốt: Tìm một nơi yên tĩnh và không có các yếu tố gây xao nhãng. Hiểu rõ vấn đề: Thay vì chỉ ghi nhớ, hãy cố gắng hiểu rõ bản chất vấn đề và làm thế nào để ứng dụng nó vào thực tế. Áp dụng các phương pháp học khác nhau: Học qua video, sách, thảo luận, hoặc thậm chí giảng dạy lại kiến thức cho người khác sẽ giúp củng cố kiến thức sâu hơn. Lặp lại ngắt quãng (Spaced Repetition): Ôn tập kiến thức theo các khoảng thời gian đều đặn để đảm bảo nhớ lâu. Luyện tập giải bài tập khó: Đặc biệt với các môn như toán học hay lập trình, việc luyện tập giải các bài tập phức tạp giúp bạn rèn luyện khả năng tư duy logic và kỹ năng giải quyết vấn đề. Ngủ đủ giấc: Giấc ngủ giúp củng cố trí nhớ và tăng cường khả năng tư duy. Học từ những người giỏi hơn: Bạn có thể học hỏi từ những thần đồng hoặc những người xuất sắc hơn thông qua sách, video, hoặc thực tế giao tiếp. Tập trung vào hành trình của chính mình: So sánh với người khác có thể làm bạn mất tinh thần, thay vào đó hãy tập trung vào quá trình phát triển cá nhân. Đặt mục tiêu dài hạn: Hãy luôn nhắc nhở mình rằng thành công không đến chỉ sau một đêm, và bạn đang đi đúng hướng.  ( 4 min )

Why CSMs Notice UX Problems First I’ve been in Customer Success long enough to know that when something’s not quite right in the product, it usually shows up in my conversations before it shows up in a support ticket. Maybe customers won’t outright say, “we have a UX problem.” But they’ll ask the same question three times, avoid certain features, or quietly disengage. I’ve learned to pay attention to that. The clues are often buried in our metrics. They're not the most obvious hints, but when you’ve seen enough of them, patterns start to emerge. That’s when you realize you’re dealing with something beyond a CS issue, and you’ve got a UX problem on your hands. In this post, I’ll share the CS metrics I’ve learned to watch closely, how they can reveal hidden friction in the user experience,…  ( 7 min )

🚀 FSCSS @fun Guide: Supercharge Your CSS with Modular Magic Welcome to the world of Figured Shorthand CSS (FSCSS), where the @fun directive is your secret weapon for crafting clean, reusable, and scalable stylesheets. Think of @fun as a superpower for defining modular style blocks—variables, properties, or entire design systems—that you can sprinkle throughout your CSS with ease. Ready to level up your styling game? Let’s dive in! @fun? The Big Picture The @fun(name){...} directive lets you create functional blocks—named containers for style values like sizes, colors, or property sets. You can then reference these blocks anywhere in your stylesheet using intuitive dot-notation (e.g., @fun.name.key.value). This approach keeps your styles organized, reusable, and ridiculously easy to ma…  ( 5 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My journey into HTTP response optimization began during a project where we needed to serve large datasets to web clients efficiently. Traditional approaches of building complete responses in memory before sending created both latency and memory pressure issues. This challenge led me to explore streaming response techniques that could dramatically improve both performance and user experience. The breakthrough came when I realized that most web frameworks treat response generation as a monolithic operation, missing opportunities for optimization through streaming, compression, and intelligent buffering. My research revealed a framework that implements sophisticated response handling patterns optimized for both throughput and latency. HT…  ( 9 min )

I built myprofile.lol – a Linktree alternative with ShareX integration Hey, I’m a computer science student, and I set myself the goal of building and launching one project every semester. This time, I spent around 6 months (mostly evenings and weekends) building something that technically already exists – but I wanted to learn and do it my own way. It’s called myprofile.lol – basically an all-in-one Linktree alternative combined with a ShareX uploader. Upload and share screenshots or files directly via ShareX Create a customizable "link-in-bio" profile with: Background effects (gradients, patterns) Animated username effects Badges to highlight achievements or important links Spotify integration to show what you’re listening to Edit Open Graph meta tags (title, description, preview image) for better link sharing Choose from vanity domains like aimbot.lol, mylinks.zip, or even stalker.zip (just for the eye-catcher effect) Stack: Next.js, Express, Redis (caching), Cloudflare R2 (storage), Mailgun (transactional emails) Automatic WebP conversion and compression to optimize storage Free accounts: 500 MB (optimized for screenshots) Pro: $10 lifetime (to help cover server costs) I wanted to combine ShareX integration with customizable meta tags, fun visual effects, and vanity domains – plus, I used it as a way to practice building full-stack apps end to end. UX and general performance Domain choices (fun or too much?) Features you think are missing (analytics, more profile themes, etc.) You can sign up for free and try it out here: https://myprofile.lol Thanks for reading – happy to answer any questions, and I’d love feedback from fellow developers!  ( 3 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My fascination with asynchronous programming began during a project where our synchronous web server could barely handle 100 concurrent users. The blocking I/O operations created a bottleneck that no amount of hardware could solve. This experience drove me to explore asynchronous programming patterns that could transform our application's scalability and performance characteristics. The paradigm shift came when I realized that asynchronous programming isn't just about performance—it's about fundamentally rethinking how applications handle concurrent operations. My research revealed a framework that demonstrates how sophisticated async patterns can be both powerful and intuitive, enabling developers to build highly concurrent applicati…  ( 10 min )

Why I Built This One of my test environments involved automating actions on a Bitcoin-based betting platform that uses a simple interface with predictable interactions. The challenge: Answer: Yes — using only a few lines of JavaScript. The Concept Base bet starts at a fixed amount If you lose, the bet increases (Martingale strategy) If you win, the bet resets The script tracks your results in the console // Bot Made By SpheXian you can change the basebet based on you balance // Bot Made By SpheXian var baseBet = 10; // In sats var baseMultiplier = 1.10; // Bot Made By SpheXian var variableBase = false; // Bot Made By SpheXian var streakSecurity = 15; // Number of loss-streak you wanna be safe for.

This is a submission for Frontend Challenge: Office Edition sponsored by Axero, CSS Art: Office Culture. Office breaks can get dull fast — especially when everyone’s on a different schedule and you’re stuck deciding what to do in your 5–10 minutes of free time. Wheel of Fun — a playful spin wheel built with HTML, CSS, and a touch of JavaScript to help me (and hopefully you) add a spark of randomness to boring office breaks. Whenever you have a free moment, just spin the wheel — it’ll pick a small fun task to recharge your brain and make break time feel like a mini celebration. Live Demo: Try the Wheel of Fun View on GitHub I built this simple project to showcase how CSS can create playful, interactive art — not just static designs. I loved experimenting with: CSS transforms for the wheel and bulbs Smooth rotations and easing for realistic spins A colorful, carnival vibe to bring a bit of joy to the office desk Through this, I reinforced my CSS fundamentals, improved my eye for interactive UI details, and had fun turning a tiny idea into something shareable. Next, I’d love to expand it by adding more random activities, themed wheels, or even office in-jokes to make break times even more personal and fun. Feel free to fork it, remix it, or spin it your way! Thanks for reading — and happy spinning! 🎉✨  ( 3 min )

GitHub Homepage: https://github.com/eastspire/hyperlane During my final year project on distributed systems, I encountered a fundamental challenge that shapes modern web development: how to enable efficient bidirectional communication between clients and servers. Traditional request-response patterns felt inadequate for the interactive applications we were building. My exploration of bidirectional communication led me to discover patterns that revolutionize how we think about client-server interaction. The breakthrough came when I realized that most web applications still operate under outdated communication paradigms designed for static content delivery. Modern applications require dynamic, interactive communication patterns that traditional HTTP cannot efficiently provide. My research re…  ( 8 min )

Follow these steps to migrate an existing published app from manual signing to Google Play App Signing. Securely store your existing signing credentials: Keystore file: key.jks Keystore password Key alias Key password ⚠️ Important: Keep a safe backup of these credentials. You’ll need them during the migration. Google requires an encrypted export of your current signing key. In Play Console, go to: Setup → App integrity → App signing. Under “Export and upload your app signing key”, download: pepk.jar The encryption key (displayed in the instructions). Run the following command in your terminal (replace placeholders): java -jar pepk.jar --keystore=key.jks --alias= \ --output=output.zip --encryption-key= This generates output.zip containing your encrypted signing key. Open Play Console and navigate to: Setup → App integrity → App signing Click Opt in to Play App Signing. Upload the output.zip file generated in the previous step. Google will verify the uploaded key. Once approved, Google Play App Signing becomes active. From now on, Google securely manages your app signing key. ✅ Note: Your existing keystore (key.jks) will now act as your Upload Key. You can continue using it or optionally register a new upload key. For additional security, you can generate a new upload key: keytool -genkey -v -keystore upload-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload Export the public certificate (.pem) from this new keystore. Upload the certificate in Play Console as your new upload key. ✔️ Backup your keystore (key.jks, alias, and passwords). ✔️ Export your signing key using pepk.jar from the Play Console. ✔️ Upload the encrypted key (output.zip) in Play Console → App Signing. ✔️ (Optional) Generate and register a new upload key for added security. ✅ Your app is now successfully migrated and managed by Google Play App Signing 🚀  ( 4 min )

Pattern matching is a major feature in software development. While pattern matching applies in several locations, its current usage is limited to switch case blocks. I want to compare the power of pattern matching across a couple of programming languages I'm familiar with in this post. I assume that every reader is familiar with the switch case syntax inherited from C. In short: The switch clause references a value-returning statement Each case clause sets another statement; if the value matches the statement, it executes the related block case clauses are evaluated in order. The first clause that matches gets its block executed In C, case clauses are fall-through; you need to explicitly break to escape the switch, otherwise, the next case is evaluated I'll start with Java, as it was the f…  ( 7 min )

🧬 Natural Selection in Code, AI, and Generative AI Natural selection isn’t just for biology textbooks or wildlife documentaries. In the age of code and AI, nature’s greatest algorithm is making waves in how we optimize, evolve, and even create through machines. From evolving code to training neural networks, let’s explore how natural selection inspires digital intelligence. In computing, natural selection is mimicked through evolutionary algorithms, where: Solutions to a problem are treated like organisms Each "organism" is a possible answer (e.g. a string, a function, a set of weights) "Fitness" is how good that solution is The best ones survive and reproduce (via crossover and mutation) Over generations, better solutions evolve This is the core idea behind Genetic Algorithms (GAs) and…  ( 5 min )

🔢 The 3x + 1 Problem (Collatz Conjecture) Mathematics is full of mysteries, and one of the most deceptively simple yet unsolved problems in number theory is the 3x + 1 problem, also known as the Collatz Conjecture. It’s a number game that anyone can play, but no one has been able to solve completely. It has captivated amateur enthusiasts, professional mathematicians, and curious minds for decades. Start with any positive integer. Then follow these rules: If the number is even, divide it by 2. If the number is odd, multiply it by 3 and add 1. Repeat the process with the resulting number. Eventually, this sequence of operations always seems to reach 1—but nobody has proven that this is true for every possible positive integer. Let f(n) be a function defined as: Starting from any positive …  ( 5 min )

Nowadays, business decisions are guided by data more than ever! From assessing product performance to optimizing user experiences, data has become a core foundation of how SaaS companies operate and grow.  However, when data is not presented in a clear and structured format, it can quickly become overwhelming. Teams may be faced with dense dashboards filled with numbers, struggling to identify key insights — what to prioritize, what’s performing well, and where improvements are needed. This challenge highlights the importance of data visualization in product development. Instead of forcing teams to interpret insights from raw tables or scattered metrics, effective visualizations organize complex datasets into charts or graphs that are easy to read, compare, and act on. This reduces frictio…  ( 8 min )

GitHub Homepage During my junior year studies, server-side push technology has always been a key focus area. Compared to traditional client polling, server-side push enables true real-time data transmission, significantly improving user experience. Recently, I deeply studied a Rust-based web framework whose Server-Sent Events (SSE) support gave me a completely new understanding of modern push technologies. In my previous projects, I tried various traditional push technology solutions. While traditional Ajax polling is simple, it's inefficient and wasteful of resources. // Traditional Ajax polling implementation class TraditionalPolling { constructor(url, interval = 5000) { this.url = url; this.interval = interval; this.isRunning = false; this.timeoutId = null; } star…  ( 8 min )

If you’re building any kind of image uploader for a website, you’ll quickly realize that a basic file input isn’t enough. The moment a user tries to upload a large file, the experience breaks. They click “Upload,” the browser seems to hang, and they have no idea if it’s working or broken. This is the exact moment you realize you need a progress bar. The thing is, building one from scratch is a classic developer trap. It seems straightforward, but you soon find yourself deep in the weeds of XMLHttpRequest objects, event listeners, and DOM manipulation. It’s a ton of boilerplate for a feature that should just be standard. Let’s walk through how to build one manually, and then I’ll show you why we ensured you would never have to.

In React, components are the building blocks of your UI. One key concept that every developer should understand early on is the difference between stateful and stateless components. This distinction plays a big role in how your application behaves and how maintainable your code is. A stateful component is a component that manages its own local state using hooks like useState or useReducer. Holds and updates state internally. Reacts to user interactions or lifecycle events. Re-renders when the state changes. import React, { useState } from "react"; function Counter() { const [count, setCount] = useState(0); return ( Count: {count} setCount(count + 1)}>Increment Hello, {name}! ; } This Greeting component simply displays the name it receives. No internal logic — just UI. It’s stateless. Separating stateful logic from presentation improves: Code reusability: Stateless components are easier to reuse. Testability: Pure functions are simpler to test. Readability: Clearer separation of concerns. A common practice is to extract state management and side effects (like data fetching) into custom hooks or container components and keep UI components as stateless as possible. Feature Stateful Component Stateless Component Holds local state ✅ Yes ❌ No Triggers re-renders ✅ When state changes ✅ When props change Reusability 🟡 Less reusable (tied to logic) ✅ More reusable Testability 🟡 Slightly more complex ✅ Easy to test (pure) React Docs – Components and Props FreeCodeCamp – React Guide  ( 4 min )

Manual testing isn’t just about following steps — it’s about thinking critically, spotting gaps, and collaborating for quality. Introduction: Why Manual Testing Still Matters Through my role as a QA, I’ve refined a simple but powerful approach: once test cases are derived from user story acceptance criteria, they undergo a three-way review process — by a fellow QA, a developer, and a business stakeholder.
